I posted this 2 days ago in the lighting forum and got ZERO responses. I am ready to pull my hair out and looking for any advice to try.
Main tank is a 210 (72x24x30H) Lighting consists of 120 XPE and XPG Crees w/ 70* optics, 14" off the water. RBs at 68% and CW/NW at 65%. RBs on at 0900 to 2200 w/ a 2.5 hrs ramp up (10%-68%) and 2.5 hr ramp down. CW/NW on at 1130-2000 w/ a 2.5 hr ramp up (10%-65%) and 2.5 hr ramp down.
Corals (99%) SPS are growing GREAT! Great color, great polyp extension, etc. FWIW, flow is MP60 and 2x MP40, all 3 W-Es models at about 60-70%. SPS from the bottom to the top. Highest SPS is 12" under the water.
Frag tank is where the problem lies.
28x20x14H acrylic. Same water as DT, fed from manifold at return pump. MP10W-ES powered at about 40-80% (experimenting). LED lighting consists of 24 XPE and XPG (12 each RB and CW, non-dimmable, at 100%, no optics) Fixture mounted about 14" above water; SPS frags from main tank average 8-10" under water.
Same water, same LEDs, same corals as DT show very little PE and in general look unhealthy. I started the light about 12" over the water, then moved it up to 14" or so, now it sits about 16" on top of a piece of 1/4" glass (thinking I was giving too much light) Also have a ricordia rock and an acan in the frag tank that look great. Only the SPS look like poo.
Anybody have any advice comparing fixtures? Thoughts?
(The only difference I can think of is the frag tank has about 15-16 frags of Zoas (150-200 polyps maybe) I plan to sell them all, but could there be chemical warfare in a tank that small affecting the SPS? The zoas are on the bottom and look great. The SPS are the only thing struggling. The DT has the same amount of zoas I cannot get off rocks, but the water volume is much greater.
