Corals 101

Corals 101

Whether you’re new to reef-keeping, considering starting your own reef tank, or just finished cycling your tank, you'll end up wondering, “What corals should I get? It is easy to get a bit too excited stocking your first tank with beautiful and exotic corals. The issue is that some of these corals need specific conditions, which can be incredibly difficult and or impossible to achieve when starting out. Although it is very possible for beginners to achieve great success with more difficult corals, the likely hood of them surviving goes down drastically. Unfortunately getting in over your head at the start can lead to losses in money, motivation, and can ultimately cause people to leave the hobby before they really even start. The corals listed below are some of our favorites when it comes to hardy corals that are also easy on the eyes, making them ideal corals for beginners.

Zoanthids, Palythoa, and Protopalys are all extremely hardy coral. You’ll often find multiple polyps attached to a piece of reef rock, often coated with coralline algae. It’s a great way to add corals and seed your tank with purple and pink coralline algae.

Like mushroom coral, Zoanthid morphs are often sold with highly descriptive names like “Grandmaster Krakatoa” and “Cinnamon Apple”. These are often some of the most desirable and beautiful species, depending on ones opinion. Although, there are also plenty of zoanthids sold in the hobby with no name, that hold just as much beauty.

Zoanthids come in a full array of color combinations including orange, green, red, yellow and blue.

Give this coral medium to high light and they’ll spread across the rock, creating a carpet of vibrant color. Zoanthus enjoy medium water currents and will filter-feed on baby brine shrimp and micro pellets.

Many people have fallen in love with "nano reefs" which zoanthids are great for, there are countless beautiful pictures online of peoples Nuvo 10 gallon nano reefs, stocked to the brim with softies.


Mushroom corals are a great choice for a beginner reef tank as they require low to moderate lighting. These soft corals are available in several colors such as metallic green, green-striped, blue-spotted, red and metallic blue. Keep in mind there are many varieties or “morphs” in the world of mushroom corals. These generic names are created to describe the look of the morph but aren’t governed by any scientific rules.

Actinodiscus mushroom corals should be placed low or mid-height inside the tank. If the water flow is too strong they won’t fully expand, so keep them in a calm area of the tank.  You can feed each polyp with microplankton coral food OR you can also add food to the water flow. And, over time mushroom corals will reproduce and spread out on the rock. Mushroom corals are also extremely easy to propagate, all you have to do is cut a specimen symmetrically in half, and boom, you have two mushrooms. Many fragging kits are bundled and sold to make fragging easier for you.

These mushrooms thrive in lower light and slow flow rates. They make great corals for nano tanks or at the bottom of larger reef aquariums. 

Pulsing Xenia

Pulsating Xenia, also known as Waving Hand Coral, is also hardy. The branched stems sway gracefully while their tentacled polyps pulse in the water. The movement creates an almost alien landscape in a tank. I personally think it’s very relaxing just to gaze at them for a period of time. They really give your tank a certain quality of “liveness.” Although Xenia is known to be an extremely hardy species, it is still recommended that you solely use water produced by a Reverse Osmosis unit. These units help to remove contaminants commonly found in tap water that would otherwise harm a coral reef.

Xenia contain symbiotic algae but are capable of filter-feeding. They thrive under moderate lighting and medium water flow. Xenia will reproduce and spread throughout the tank. If you happen to own one, you already know they grow like weeds in a healthy aquarium. In fact, you probably have reefing friends that may offer you a branch or two.

Some aquarists surround their colonies with loose rubble pieces. When the colonies spread to the rubble piece, they’ll pull the piece away, and they trade them in at their local fish shop or reefing club. There are many ways to enjoy reefing, with the emphases on "enjoy"!  Happy reefing.

"10 Upgrades to Dalua’s DC Great White Protein Skimmer" - Reefbuilders

"10 Upgrades to Dalua’s DC Great White Protein Skimmer" - Reefbuilders

The Great White from Dalua Australia is one of the best value protein skimmers in the reef aquarium hobby and now Dalua is doing the same for controllable DC skimmers. The new Great White DC skimmer is much more than just a DC powered version of the original sporting ten improvements to the design for even better performance and ease of use. 

Building on the success and widespread popularity of the original Great White skimmers, Dalua doubled the number of sizes in the range and developed four different models of the Great White DC. The larger GW10 was probably the most popular size in the original line and we’ll be comparing it to the similarly sized Great White DC12 to see all the ways that the new models have been improved. 

1. DC Needle Wheel Pump

The inclusion of a DC Pump is clearly the most obvious new improvement to the Great White Skimmer offering improved performance, quieter operation, and reduced power draw. The larger needle wheel also draws in more air than the similarly sized AC pump so there’s even more foam to carry away all the unwanted nutrients. 

2. Controller w/ Functions 

Just because most DC powered pumps are controllable, it’s actually much cheaper to make a non-controllable, one-speed DC pump. You would still get the primary benefits of reduced power and silent operation, but you need some electronics to make them speed up or ramp down, or go into pause/feed mode for a period of time. 

3. 3D Printed Venturi Valve

Besides the controllable needle wheel pump, perhaps one of the most interesting new improvements to the new Great White DC skimmers is the use of a 3D printed venturi valve. By printing their own aspirating mechanism for each pump and skimmer model, Dalua can do a lot more fine tuning to the performance of the skimmer getting the ratio of the air/water mixture just right. 

4. Larger Thumb Screws

The thumb screws included in the base of the Great White DC skimmer are much larger and much easier to handle, especially for guys like us with big sausage fingers. 

5. Bayonet Neck Fitting

The new Bayonet locking neck is very smooth and very easy to engage and disengage which will make removing and replacing the cup easier than ever, and possible to do with one hand on the GW12. 

6. Reduced Clearance Required

The GW12 DC is about one inch shorter than the GW10 but due to the new bayonet neck fitting there’s even less clearance required to remove and replace the collection cup. The GW10 is 23 inches tall but requires an extra inch of clearance, 24 inches or 60cm in total while the GW12 is 22 inches tall, but only needs 22.5″ of clearance; this sounds like a small difference but it’s the best approach to pack a ton of power into a modern, compact all in one sump for smaller reef tank setups. 

7. Wider Neck

The width of the neck on the GW12DC may only be half an inch wider in diameter than the GW10, but this translates to a 30% increase in the surface area. The wider neck works better in regular seawater salinity environments making it capable of producing thicker foam, but most of all it should be much more stable at skimming marine aquarium water. 

8. Larger Reaction Volume 

The wider neck is not limited to the collection cup as the conical portion of the body is also wider in cross section at the top. This wider path also creates a larger reaction volume for more reaction time, and a skimmer that is generally better at processing a foam of air & water. 

9. Larger Drain Hole 

Since the Dalua Great White DC 12 can produce more skimmate than ever before, the larger drain hole will make it simpler for users to use a protein skimmer waste collector remotely from the primary filtration area. 

10. Integrated Air Silencer

The new integrated air silencer is a circular ring that forms the bayonet where the cup locks into the body of the skimmer. Unlike typical small air silencers the circular design is concentric and reduces the noise of the air intake which is more important than ever since the GW12 pulls in an estimated 50% more air than its predecessor.

DALUA Australia enters the US market with the new skimmer: Detailed Review.

The question that always makes me concerned is the cleanliness of the water in my reef tank. So in my article today I would really like to answer the question of how it is possible to keep the tank clean from food and other organic waste that can cause the harmful environment for the corals and fish. As you know I’m a big fan of the water changes and you can check my full article on this subject here - Clear Advice – Exploring Reef Tank Water Changes. I replace at least 10% of the water in my reef tanks every week. When only water changes are enough to keep your nutrients in check for low stocked tanks, for larger and heavily stocked aquariums a right filtration system is crucial for the organic waste that is constantly growing in your tank. You might choose using only biological filtration to deal with this problem, but experienced reefers are using a protein skimmer because it has a range of advantages that will be revealed in my article below. For now I will just say that it is worth considering for those who have a saltwater aquarium.


As a lifelong aquarist, Yuliya has an endless curiosity about our underwater universe. After graduating with a bachelor’s in Environmental Engineering, she transformed her passion into a successful career. While working at the Institute of Environmental Protection in Moscow, her passion for saltwater and reef aquariums only increased. Moving to the United States in 2013, Yuliya embarked on another impactful journey by sharing her unprecedented experience for all aquarium hobbyists ... Read More.

Let’s get down to business, are protein skimmers necessary?

Skimmer cleans the water in the tank by removing organic waste from the water before it has a chance to break down and release nitrogen compounds back into your reef tank, which will affect your nutrients levels. This device makes your aquarium a healthier place for its inhabitants because parasites and other harmful microorganisms prefer to live in a dirty environment. So the main benefit of using a skimmer is that it could reduce the number of diseases among your aquarium creatures by keeping your nutrients levels in check. Click here to earn more about Nutrient Export Method Hack and How To Choose Your Ideal Method.

Secondly, skimmer helps you in a battle with algae that can really destroy all your efforts to keep your reef clean and thriving. And also, as a positive side effect, more light will pass through your aquarium, providing corals growth, and in prospect, corals will have more intense color.

Finally, organic compounds floating in the water can change the pH level. Unstable pH level is one of the factors that make a bad influence on life in your tank.

So what’s the secret, how does the skimmer work to prevent pollution of your reef?

As you know, as an engineer I love technical things, investigating how they work and making some scientific research. I am always amazed by protein skimmers, how effective and easy to use they are. Simply put, protein skimmers clean the water by the attraction of organic molecules to the thousands of air bubbles, which then move to the waste container. It’s easy isn’t it?

The liquid then becomes dark and dirty - it is called skimmate and should be emptied before it has a chance to overflow back into your tank. Can you imagine that all this was in the tank but invisible to eyes? I am sure, every reef aquarium will benefit from a quality protein skimmer. I don’t know a better way to remove organic waste from the tank. For instance, a mechanical filter can trap some visible particles, but if it has not been cleaned, in time all the nutrients will release back into the aquarium. Instead, protein skimmer pulls the waste out the water and you only need to clean the container. If we continue to compare protein skimmer with chemical filters, we will also find some further advantages of the skimmer. These two methods have a similar aim - to keep your reef tank nutrients levels in check. A chemical filter absorbs waste into chemical media, and when it is filled up it should be replaced. If you forget to do it, all pollutants can leach back into the tank.

A protein skimmer, on the contrary, has an endless surface to absorb waste due to the constant generation of air bubbles, all you need to do is to keep an eye on the collection cup. Protein skimmer is crucial for marine aquariums with sensitive reefs and heavily stocked aquariums.

So what’s it all mean?

Protein skimmer prevents your inhabitants from different diseases, stops aggressive growth of algae, cleans the water from visible and invisible toxic compounds and makes the saltwater clear and your corals flourish. OK, I know what you’re thinking ...

What protein skimmer should i get?

There are a lot of quality products in a category of protein skimmers and one of the remarkable models which worth your attention is the Skimmer Model GW-10 by Dalua Australia. For a very long time, I wanted to get in hands this skimmer for a test and finally, my dreams come true.

Dalua Australia is famous for its filtrating and LED lighting systems. At first, I saw this company at one aquarium exhibition, where they presented their products. Sometimes it is important not only to see the logo of the brand but also get to know, who stands behind the product. The team of this company consists of passionate manufacturers, who find the best solutions to make great quality products. They even called their new model of skimmer - Great White. The background story of developing this skimmer was just amazing. Can you imagine that these guys have simply used a standard skimmer model for their research with the hope to improve it and make it more user-friendly? With so much passion, there is no surprise that they succeeded in that. Together with changing technological and design features for the new model, they also put an extra effort to make it upgradable, which means that Co2 scrubbers and lanthanum chloride drips can be added directly into the venturi. If to forget about skimmers for a short while, their overall product range combines great quality with attractive design. I know, that this brand is new in the USA but I believe that soon it would be well-known among reef-lovers. 

Now let’s take a closer look...

Benefits of Skimmer Model GW-10 by Dalua Australia.

Great White Skimmer includes 55W Italian made AC Eden pump, which provides strong skimming power to produce an enormous amount of air bubbles every second. On top of all the technical advantages of this skimmer, the thing that I appreciate a lot is that it is super quite. My test showed only 52 decibels rating which is a very nice result for a skimmer of that size. Moving closer to its capacities, it is able to filtrate up to 500-1,000 liters (up to 260 gallons) of water with an impressive air intake of 400-750lph.

This brand provides post-sale assistance and professional customer support service, ready to answer all your questions even in social media and reef forums like, which also adds proses to this particular brand. Along with I have to mention that the quality makes me believe it will be trustworthy and long-lasting as the main part of the skimmer is made from high-quality acrylic. What also I like about this skimmer is that here is employed in my opinion the most convenient mechanism for water level regulation. To raise the water level you should rotate regulator in the minus direction - it will restrict water from leaving. On contrary screwing regulator in the plus direction will drop the water level. It is very simple and standard mechanism that allows you to make precise water regulation without any difficulties.

What else? After purchase, you get it in separate parts but it is very easy to assemble. You don’t need any hand tools. Every detail is developed that way that it is suitable for screwing by hand. So the setup of this device is pretty easy even for those who have never done it before. But I'd like to see a connector/stand for the pump in the next versions of this skimmer, this would be much easier to align the pump inside the air chamber. At this moment it's just standing on the bottom of the skimmer on rubber feet and you need to make sure that the bubble diffuser plate is aligned well on the center before you start using it.

Naturally, for a passionate reefers not only the technical side of the product matters but also the design. My new GW-10 skimmer is quite similar to other skimmers of the class - it has a conical body, which makes it compact and a good fit for even very tight space. Along with, the cup is large and it is very easy to clean it. However, there is one visual feature of this skimmer that makes it remarkable among other skimmers - it is an uncommon design of bubble diffuser plate. In contrast to other skimmers, it has holes along all perimeter of the plate, while the most common design is to have holes on the top. Overall, the design of the skimmer looks excellent to satisfy enthusiastic reefers.

You can buy this skimmer from our friends at Unique Corals by clicking here.

From Australia with Love, Skimmer Model GW-10 - Final Thoughts.

In closing, I want to summarize that this skimmer is a great choice for an affordable price. It delivers constant cleaning to your aquarium and due to its capacity, it can be adjusted to the tanks of different sizes. It does everything it was bought for. So my first experience with a new brand in the USA market - Dalua Australia was great and I can’t wait to see more products released by them.

Be sure to follow their Facebook Page, and while you’re at it, send us a message with any questions you may have. Although mastering the artform of reefing is a lifelong journey, you aren’t alone! As always,

Happy Reefing! by Yuliya Ivanova for ReefHacks.

The Great White Protein Skimmer Product Review by Afishionado for

"Last year during MACNA, I was hanging out and talking to my friend Sanjay Joshi and like we do at every trade show, I was asking him who he thinks that I should talk to and which product that I should check out. As soon as I said that, he led me to Dalua Australia's booth and introduced me to Christian and Anthony. Fast forward few months, here is what I found out personally about their flagship skimmer, appropriately (in my opinion, it catches the Aussie vibe very well) named Great White Shark skimmer. Check it out." - Afishionado
