The 3 metal halides are 175W, two metal halides are the blueline bulb and one is a 50/50. The Acro's are proprogated, the water perimeters are salinity 1.025, calcium 450, iodine 0.6, phosphate 0, nitrate 0.5, alkalinity is 5.50. I don't know what type of lights the Acro's where under before I got them as I bought them from FFish. I have had them about 3 months and one of them is bleaching from the bottom. I use Marine Snow about every other day. My tank is 75 gallon and has the following: torch, brain, leathers, xenia, anthelia, mushrooms, polyps, frogspawn, pipe organ, long tentical plate, pagoda's, gonipora, colt.
It was suggested to me from FFish that I was not leaving my lights on long enough. I have one blue spectrum to come on at 9 and cut off at 12 and then the other two come on at 12 and cut off at 5 and then one blue comes back on at 5 and cuts off at 8. They also said that my salinity was too low so I raised it to 1.025.
Hope this helps! :)
