I have a 90 gallon tank I used to have two 4oo watt mogal metal halide lighting with luminarc reflectors, I switched to a Ati Sunpower 48 inch 54 watt T5 light with 3 Ati bluplus 1 fugi purple 1 GTE 75/25 and an ati aquablue. When I first fired up the new t5's I was like wow the colors were amazing! But now about 4 weeks later all my Sps are turning white, and the colors are declining. My Lps corals are fine It's just the SPS corals, I don't know what to do I have a lot of money into this tank and I'm very discouraged. I am running a calcium reactor and just started a Phosfate reactor because also since the light change I am having a bubble algea problem. I have done two 20 gallon water changes within the last 10 days also have added fresh carbon. I use Tropic Martin Pro reef salt.
My PH is 8.5
calcium 450
KH 12
nitrate 0
nitrite 0.25
ammonia 0.25
The nitrate, nitrite, and ammonia are a API test kit so not to sure how accurate it is.
