My reef is a 90 gallon with a 27 gal sump. I have the euroreef cs-2 protein skimmer. My water conditions are 1.022-1.023. Ph is fine-8.1-8.2. Nitrates are 20ppm. I am currently using the coralife 4 x 96 power compact lighting system.
Thanks for the welcome.

Seems like your reef does not have enough lighting. PCs don't penetrate very well. Their PAR is like three inches.
Its not about wattage per gallon...its about how intense and how much par the lights are putting out. If I remember correctly, PCs put only about 3 inches of PAR out. Thats nothing compared to the certain T5s that can put out 18 inches. Not to mention PC is limited to what spectrums they can have. When I went from PCs to T5s, everything in my tank took off. It was a great investment.<a href=showthread.php?s=&postid=8072310#post8072310 target=_blank>Originally posted</a> by Marko9
So 384 watts is not enough for a 90 gallon reef tank?

A Power Compact tube is essentially T5 technology, except PC's are rarely overdriven and the design/reflectors are inefficient. If you stay with higher PAR tubes, i.e. 10000K down to 5500K then at BTA will likely be fine.
