This guide endeavors to assist you with the ever popular SPS coral. This was written by member Shadowramy and it explains specific ideas and strategies in which you can do to affect the color of your corals. This assumes you have a more then basic understanding of water parameters in your tank. Click the read link to start reading about coloring in SPS corals.

In the past I have been asked a lot about coral colorization as well as wanted to satisfy my own curiosity about specific methods to achieving certain colors. Usually I am asked, “How do you get good colors?â€Â Which I then ask, “What specific color are you looking to enhance?â€Â Over the past several months I have really worked on “tweakingâ€Â colors and what is needed to get certain colors. I have done my own testing as well as seen a lot of others tanks and what they have done to achieve certain colors. I think I finally have a basic map for those who are interested.

Please note: I am assuming that you meet the minimum suggested standards to keeping SPS; strong lighting, calcium at the appropriate levels, strong skimming and live rock.

Yellows

Highly dependent on Nitrate and PO4 levels. Of course all SPS colors are highly dependent on lack of N and P so I wanted to start with probably the easiest color to get, yellow. Yellows are sort of you baseline; yellows will tell you a lot about what is going on in your tank, what is needed and what is overdosed. Nitrate and/or PO4 reduction is most important, either through technical means such as nitrate/phosphate reducers or biologically through DSB, Carbon dosing and/or water changes and fuges. Basically, if you want to do SPS, I would suggest starting with an acropora that is yellow. If you can get it to say yellow for several months, you should be ready for something else.



Greens

Greens would be the next easiest color to tweak. Most green coloration can be achieved through the addition of an Iron Concentrate (Kents is what I use, however Iron is Iron). You must be very careful with Iron because it is also an Algae accelerator; this is why it is so important for you to get your yellows colors first (your N and P will be lowered).

Additionally, I use my yellows as indicators for my greens and blues. You’ll notice a deficiancy if your greens are brown color or they are paling in color. I start off by dosing Iron at about 1 drop per 50 usg twice a week and take note of what happens, color changes, Algae growth, until my yellow acroporas display a green shimmer (it wont be a solid green but a shimmer of a green/yellow).

Please note, a sign of overdosing is a darkening of tissue, when this happens you have added too much iron or too much iron is being added. Another sign of overdosing is Algae growth, stop immediately and possibly do a water change if necessary. Like everything else reef, go slowly.


Blues and some purples

This is mainly for blues but I have found is can also have an effect on purples. The supplement for this is Potassium Iodide Concentrate or Lugol̢۪s solution, ESV Potassium Iodide Concentrate will also work; don̢۪t just get something that says Potassium because that is a little different. Dosing should be done when blue colors become less intense. Again, using yellow corals as indicators, stop dosing when yellow corals display a green shimmer.



Reds/Pinks and some Purples

Primarily for coloring reds and pinks in Montiporas, Pocilloporas, Birdsnest, other Stys and Seriatoporas. The supplement is Potassium (not potassium iodide). If you are using a high potassium salt mix such as Oceanic, Tropical Marine Pro and you are doing regular water changes, you are more than likely not going to need to supplement this much.

For dosing you can use your monitporas, especially caps as indicators. Supplementing is required when Montiporas display slower growth and appear washed out to grey appearance. Indicators on Stys and Pocs are when they look like they have been exposed to air. Polyps are completely withdrawn and colors are light. Other indicators of potassium deficiency is when the pinks turn into a light brown and when acroporas loose their color and get lighter and pale. A major potassium deficiency is seen when tissue is lost, mostly starting from the base opposed to spotting (patchy look). And overdose can lead to tip burning so don̢۪t mistake tip burn for new growth. Tips burns will be white with no polyps.



Purples

Probably one of the hardest coloration of all acroporas from my experience since it is a combination of several variables.

First and foremost is water clarity, which means Carbon and/or filter socks. I have also had good result from biological filters such as using cryptic zones, which produce seasquirts, sponges and other filter feeding animals. Zeo Sponge Power, which can be used in any system, feeds sponges. Sponges are great because they can filter a mass amount of water for better water clarity.

From what I have noted, increased water clarify will first effect SPS tips but not the complete base. I have seen nana and valida with really nice purple tips but brown/tan/white bases. I have seen the same nana and valida in another̢۪s tanks, which met all other parameters with a full purple from base to tip.

Second being lighting. From my observations of my own tank and others, purples seem to love 420-440nm range light spectrum, those found in actinics and 20K halides. Some of the best purples I have seen are in tanks that have 440nm blue actinics (ATI Blue+, Giessman Actinic) or 20K Halides (Radium, XM 20K).

Third, supplements such as Iodide and Potassium (see blues and Reds/Pinks). Again, make sure your greens are green and yellows are yellow. Your blue should be bright with depth. Iodide will also help if you have tip burn.

These are just my observations through testing and I am sure in the future other factors will be seen and added. Please feel free to comment with your own observations, data is very important to moving forward.

If only making corals the color you want was this easy.

I did buy and started adding some K+ yesterday. Losing the color red for some reason. Well see what happens

Start parameters:
Dkh- 10-11
Nitrate- 5-8
Phosphate- 0.4-0.7
calcium- 400-430
 
Can you prove with scientific data that everything you are saying is true? LOL, JK! Great info, thanks for sharing!
 
That p04 is ridiculously high lol.

Some of my blue acros changed color to green at that phosphate level before.

I was actually perusing that last night. To me the original individual who wrote it just pulled it out of thin air. I've read quite a few counter-claims regarding dosing Potassium, etc., not to show any effect. Also, yeah no journals either. I remain skeptical.

Richard- Although many of us strive for PHO4 <0.6, some have had good success with 1.0.

That being said, remember that even the most reef hobbyist accurate test kits have a 0.04 error margin. So a reading of 0.6, can still be 1.0.
 
Eddie - you mean .04 margin so 0.6 can be .056? ;)

I had mine at high and I got almost no growth at all. Now that I have it down to more acceptable level, they have been growing pretty well.
 
Although that sounded very informative, it also sounds like you need to dose all this stuff to get colors. I've never dosed any of that stuff, and I've had super bright red montis, I've also got a bonsai that is super blue at the tips. That info can be somewhat misleading if you are starting out. Not knocking it, just kind of a beware, I guess, LOL! Definitely interested in the whole potassium dosing, as that one seems to be very interesting for the harder to get colors. Anyone on here dose K+?

Thanks for posting regardless:D
 
i used to just dose Kalk, then seachem 2 part then I was too lazy then I found an awesome deal on a calrx and I just let that do it's thing. Everyone is happy lol.
 
Oops...
Thanks for pointing that out Rich

Po4 =.04-.07.

Danny, im dosing K+ brightwell. 50 ml per day or every other. Ill let you know what happens.

Max is 125ml per day, so im taking it slow

I also removed a HUGE toadstool today. May have releasing toxins in the tank.

This guide can be completely wrong, so be careful all

Relating to this:

This points out much of the same thing but in video format. Now I'm interested to see if my system is deficient in trace elements as I opt out of water changing. I'm also going to do some ball breaking of Red Sea specifically if they can point me in the direction of the journals for their findings.

Does anyone here actually test for trace elements?
 
So, a good salt mix, frequent water changes, stable water parameters and 20k lighting, that was a lot of reading for us picture guys.

I do dose Lugols and Ferrous Gluconate (iron), colors are better than when I didn't dose
 
IMHO- And I know you guys are tired of hearing this from me:

Holy Trinity (as my friend GasMan used to say)- Ca, Alk, Mg
SPS= Stability Produces Success
KISS= Keep It Simple Stupid

30%/monthly water changes per Dr. Randy Holmes-Farley

Period.

This is an accurate picture when using this system of upkeep. I find it a bit difficult to keep things simple in such a complex field however.
 
If your going to dose all these things don't you think you should test the levels before and after dosing? What's the target level your looking for? Should it replicate nsw? I don't think we can get hobby test kits for these? Doesn't water changes replace what we think may have been depleted but can't measure? With all this unknown I must admit I occasionally use trace products like fuel. Goes under the snake oil category. Never noticed a difference but it makes me feel good. I hope future research tells us more.
 
If you read the article above and you watch the video that fox posted, it said that K (potassium) would increase the color red.

Strangely, brightwell indicated on the bottle that K would "enhance blue coloration".

IMO- Water changes are the way to go. With one 50% or larger every now and then to get the trace elements back on track.

Yes, Marke I would recommend testing the levels beforehand. Im just increasing a small amount to see what happens as an experiment

In future, I will hopefully be switching over to NSW and larger water change schedule.

Im determined to get that shortcake colored up ( :
 
Does anyone here actually test for trace elements?

Got an ICP-Mass Spec? With only a few exceptions, most trace elements are not testable with hobbyist kits, and sending samples out to a lab gets expensive. IMO, much cheaper and easier to just keep up on regular water changes. It's time proven to work ;)

Marke/Biggar- there are K+ test kits available for aquariums. Dont know anything about them but they do exist.
 
The article is not wrong or right, from experience and trial and error I have seen the advantages of increasing the Mag adding Potassium and so on, However, the beauty of this hobby is that it is not black and white, What works for me may not necessarily work for you and the reason for this is that there so many variables involved from tank to tank, Lights, salt mixes, bio load, flow, filtration type etc etc etc.
These variables make most scientific journals seem confusing for some because they are mostly based from the ocean studies were the conditions are almost always stable or control environments like labs. Our fish tanks are all different.
Of course You must understand basic things when you enter this hobby like nitrogen cycle, alkalinity general water conditions and from there experiment with what works best for you.
This is not a black and white hobby and this is why I like it, it is constantly challenging me if it wasn't like that I probably wouldn't do it.
 
I just do my water changes like I'm supposed to and let my calrx do it's thing. Not a big fan of adding too many things lol.
