How to keep successful SPS tank

In response to a lot of questions from members of this board, regarding keeping thriving SPS tank, I put together a simple guide, so anybody thinking of jumping in to keeping SPS corals have some references what’s needed to succeed.

Keeping SPS corals is probably the highest level of reefkeeping (I am not including people who keep or breed difficult fish).We want not only to keep our corals alive, but want them to thrive, grow fast (relative term) and have beautiful colors. It is very rewarding to have a tank full of colorful SPS corals and have other people admire it. This makes the extra sacrifice, like more maintenance and of course money you need to spend, a lot easier to swallow.
In very simple terms, here are five major things you need to provide, to have thriving SPS tank. In no particular order, as all of them are equally important in my opinion.

High Intensity Lights

SPS corals are photosynthetic, that means they need light (a lot of it). You need to invest in quality light fixture. They cost more, but believe me get it right the first time and don’t go for cheap fixtures to save money. In long term you will need to most likely upgrade those cheap lights to better ones and really spend more money overall. I know something about it from my own experience. High Output (HO) T5’s, Metal Halides (MH) and LED (Light Emitting Diode) are all acceptable. I am not going to debate which one are the best, as you can have successful tank with any of those lights. Research different forums; get others opinions, to make sure they fit with your plans.

Flow

Corals live in oceans, where water movement is strong and chaotic. It is important to replicate this in our aquarium. Water brings food, brings oxygen and also washes away any debris of corals tissue. Without adequate water flow, SPS corals will slowly begin to die. Depends on what substrate you use (on none at all),I would recommend water turnover rate anyway from 20 to 50 times per hour your tank volume. I don’t include in those numbers flow generated from return pump, because I want my return flow be slower, about 5 times tank volume per hour, going through a sump, so water has more time to go through filtration system. There are many pumps and powerheads to choose from, but try to replicate random flow by using timers, or better wavemakers or controllers. Again do some research which are the best for you.

Oversized Filtration System

SPS corals require pristine water conditions to thrive. Using oversized filtration system and generally not overstocking your tank with too many fish, will accomplish just that. Start with good quality protein skimmer. I like to use one at least one size bigger, than is recommended for the size of a tank. Properly set up skimmer will pull out a lot of “nasty stuff” out of water. Skimmer also oxygenates water in your tank, and of course all livestock need oxygen to live. In addition to protein skimmer I use GAC (granulated activated carbon). Make sure to buy one that is phosphate free, as you don’t want any phosphates to be released in to water. Carbon will filter out a lot of toxins and water coloring substances that appear in aquarium. Water will look crystal clear. Next thing is to keep your phosphates as close to zero as possible. High PO4 levels prevent calcification in corals, so they grow very slow or not at all. Also PO4 cause browning effect in corals, and we strive for beautiful and vibrant colors. To keep PO4 low, it is important not to over feed your tank. An uneaten food particle breaks down and release phosphates. Don’t overstock with more fish than your system can handle. Lastly, using GFO (granulated ferric oxide) in a reactor, helps to reduce PO4 levels. There are also other forms of filtrations you can utilize in addition, like having a refugium, using algae scraper or bio pellets.

Stability

The conditions in our oceans are very stable. Salinity, temperature, calcium and Alk stay constant, or change very little in long time period. SPS corals are very sensitive to any sudden changes in their environment. To create stabile conditions in your tank, I strongly recommend use of a controller. This piece of equipment will give you great deal of control over your whole system. Light schedule, temperature, correct levels of Ca and Alk are easily controlled with it. It gives you peace of mind when you’re not home. It takes long time to have your tank look great and mature, but only in short time, when all of a sudden things get out of whack, corals begin to die. It is worth the investment, believe me.

Patience

Last thing I want to talk about is patience. Nothing good ever happens in our tanks when we rush the process. Let your tank cycle and stabilize first before adding any fish and corals. Don’t overstock. Let your corals grow. This takes time. When you start with a small frag, it feels like forever to see this thing to grow. But when it grows to a decent size you can see new growth almost daily. If you want to have natural looking, mature SPS tank, don’t frag your frags in hopes to make quick buck. I did not get in to this hobby to become rich (there are other, easier things you can do to achieve this), but to have beautiful tank that I and others can enjoy. Believe me, when you let your corals grow, you will have more than enough frags to trade or sell later. When starting new supplement or new regiment, take it slow. Give it time to work. You’ll never know if something is working or not ,if you don’t give it enough time. Changes don’t happen quickly, only for the worse. And last, don’t get discouraged if things are not working for you right away.

I hope this will help some of you that are thinking of trying SPS corals. Again, this was not meant to be detailed how to, but rather simple overview of things needed to succeed with SPS.
Good luck.
 
Great information Mark. There are so many people coming into our hobby that crave information like this...then there are people who are starting new tanks like myself....and your guide here is great information...even though we may already know this stuff.
 
Thank you guys,I hope this helps all the new people trying to keep SPS.I know most of you know all this stuff already.
 
Thank you for the valueable information. An article like this gives a newbie like myself courage and most importantly a huge sense of direction. By the way, your tank is amazingly beautiful and I will strive to one day have a tank like yours. I guess if I strive for perfection I can achieve excellence!

Thank You!
 
Great info. Any pointers on. Getting better polyp extention? My sps are growing at a pretty nice rate, but some of them like my millie and Orange digi have little polyp extention. They still have great growth though. An I've noticed at night all the polyps still get very extended to eat. Just trying to get better PE during the day.

Do you have any fish nipping your corals during a day? Any angels in your tank?
 
I don't believe i have any fish nipping on the sps. I do have a flame angel and did know the risk putting it into the tank, but i've been watching it, and it doesn't pick on the sps. (as far as i've seen). Doesn't rule out the possiblity though :( THo all my birdsnests are doing great though. Could it be something to change in the water parameters?

If your corals are growing and keeping good color I would not try to change anything.Even thought you did not see your angel pick on corals,IMO he is the suspect.

Yea... that's what i'm thinking too, but i have not caught him in the act yet...

Do you think a hermit or shrimp may do that? I have seen hermits climb my SPS before but I don't think it happens often enough to keep the polyps from fully extending?

But ya, nothing has been bleaching, and all my frags have been encrusting at a pretty quick rate.

Thanks for the info, I think i will take your advice and not change anything with my parameters, I'll just continue to keep an eye on that flame angel.
