I have been keeping saltwater fish for about 30 years now, and a couple of months ago decided to try my hand at corals. I have a 120 gallons tank that has been established for 7 years now. I also have quite a bit of live rock. I decided to go with the Aquaillumination HD32 lights, of which I have three set for the Saxby settings mounted about 8 inches above the water. I have three bubble tip anemones which seem to be doing very well, a couple of emerald crabs, an arrow crab, two fire gobies, two tomato clowns, two occellaris clowns, three skunk clowns, a sailfin tang, a bi color blenny, a six line wrasse and a hawkfish.
My issue is I can't seem to keep the corals alive. I have two zoa frags, a toadstool, a green star polyp frag and a purple hair mushroom, and two that I don't remember what they were, but tey looed awesome. None of them seem to be doing well. I also have started to notice a brown stringy algae that is forming on the back glass, the rocks and on the toadstool.
For equipment, I have a Fluval FX6 canister filter, a HOB refugium with algae to absorb phosphates, and two Jabao wavemaker powerheads. I also have a doser that delivers 20ml of reef food a day.
Chemistry is as follows...
Salinity 1.025
Temp: 79.2
Ca: 420
KH: 9
Mg: 1400
Silicates: 0
Phosphate .03
Ammonia: 0
Nitrite:0
Nitrate:0
pH: 8.2

Any ideas what I should do next? I have no clue what to do now.
