How to improve coral color???

Its time to start tweaking again. I want to see if I can get more vibrant color out of my SPS, like some of the tanks I have seen here on RC. I have a 300 gal main tank, 180 gal refugium, water params are all good, the lights are 4X 175W MH and 4X 96W Actinic. What should I do to improve the colors? The obvious one to me is lights, go to 400's but does that really matter? The tank is only 24" high and most of the SPS sit fairly high up.

Thanks,

You don't need 400's on a 24" deep tank but 250's might be better than the 175's. I swapped from 150's to 250's on a 21" deep tank and my colors improved. However as you know lighting is only one of many many things that affect color.

I have been using the Zeovit for about 9 months and have great color even after moving two times. Their are plenty of Zeovit naysayers but most have never tried it, sure it is not a miracle cure but it does bring out more color and growth once you have gotten your tank parameters correct.

If your parameter are all fine and you have good flow. Than higher light is the key. IME, 250w is good but 400w with 14-20k will improve the color that much more.

go with more lights, you said you got a 300 gal right, just go with more lights (400's), keep water clean and stable.


and do you have any pics of full shot tank pics.

deffinitely go with new lighting, 250 radium or helios, bring out the colors.

Zeo is another answer, but it is expensive and time consuming, and your params got to be dead on, but it does work, I have seen many amazing tanks that run ZEO, but it is not for everyone???

Havent heard mention of flow yet. IME equally as important as light.

Flow is WAY more important than light.


If you're unhappy with the lights, try the 175 Iwasaki 15K bulbs. They've got as much par as most 250w bulbs, and are really nice looking.

An interesting obseravtion I can add to this. I recently (few weeks ago) turned one of my CL outlets to blow directly into one of my main acro patches in my tank. A tiny portion of a green table acro now gets hit by that current. Since then, that particular part of the table has grown more than the rest of the colony, and taken on a ridiculous glowing baby blue that previously only the axial coralites had on the colony. Anecdotal, I know, but still pretty interesting I think. I'll try to get the underwater camera in there to take some pics...

I completely agree that flow is more important than lighting! In order of importance IMO…

Water quality
Flow
Lighting

One thing to remember is that flow can really help increase your water quality so really water quality and flow go hand in hand and are equally important. Once you get your water quality good and flow good upgrade your bulbs to the 175W reeflux 10K Bulb and you will have great colors. I am using 4 175W reeflux 10K Bulbs right now and in just a week I am already noticing my corals color improving! 10K bulbs are great for producing color and growth in SPS IMO. If you replace your PC actinics with VHO super actinics they will look as good as any of the higher K bulbs IMO. Just a few thoughts…

I use 2 175w 10K Ushio w/one 03 VHO and one 10K VHO and I love the color of light. The sand is wedding gown white and really pops. As for sps, I get extreme color and growth in the top 1/3 of the tank.
