Zoanthid color darken. not enough light?

[CaptNemo]

Hello everyone,

I used to have a 70W MH over a 20gallons High tank (aga). The MH is about 4 inches above the water. the color of bam bam zoanthids was bright orange. now i upgrade the tank to a 37 gallon oceanic tank with the high of 21". I also upgrade the MH to a 150W double end light. the light is now also above water about 4-5 inches. The problem is this. my green/pink tip frogspawn and my bam bam zoanthid's color is less bright. the bam bam is darken and frogspawn not as green. What is going on? is it becuase i just move them over the new tank? it has been is the new tank about 3 weeks now. or is it becuase of not enough light? What do you guys think? i am just keeping zoanthids , frogspawn ricordea, gsp, and mushroom. do you guys think those corals will thrive and keep the bright color under this 150W MH under the high of this tank?

thanks.

I doubt its the light. Because its a new tank you probaly have high No2 and No3 and high nutrients. They sound stressed and in time should brighten up. Good luck

Also did you change the kelvin rating on your bulbs?

YEA, check the K on your bulbs. I also had a 70watt sunpod MH with a 14k bulb. I upgraded to the Sunpod Orbit series with a 150k MH with a stock bulb of 10k. The 10k was much to white and washed out the colors of my reds/oranges. The blue/greens were not as bright either. I changed back to a 14k bulb and my colors were back. Big difference !! My best colors are when the MH is off and just the 2 spectrums of T5 actinics are on. The color is unbelievable !! I never knew what a difference bulbs make. My original sunpod did not have the actinics, just MH and moonlights.
