I have had my 60 gal set up for 7 mos. and have a variety of corals. Some seem to do fine and have good but not great color-- montis, grn leather, star polyps, acans. Others very little growth and washed out color-recordias, birds nest, palys, some zoas, xenias. My Parameters are:
CA 700
Phos .07
KH 7
MG 1200
K 401
Temp 78-80
Sal 1.026
Lighting consists of (2) 55 watt power compacts 6700k; (2) 55 watt actinic blues power compacts. These run 12 hrs. (2) Hamilton MH 250 watt 10K these run 3 hrs AM and again 2 1/2hrs PM. I know my sal and CA are a little high I'll fix that today but I suspect I may need more MH light time but how much more I don't want to burn them I upped the time about an hr couple of weeks ago but don't see any difference. Advice?
