I have a 125 gallon SPS dominated tank (mostly small colonies and frags at this point) and I'm wondering if my lighting levels are sufficient. I've begun to see some signs of browning in my SPS and I'm trying to take the necessary steps to bring coloration back. Polyp extension is very good on all corals I currently have an AquaMedic Ocean Light with 2 X 250W MH Phoenix 14k + 1 X 54W Coralife Daylight T5 + 1 x 54W Coralife Actinic T5 placed about 8 inches above the water. It is very bright, but I'm not sure what my PAR levels are. I have the AquaMedic comination ballast driving all lights.
I'm currently at 5.06 watts per gallon.
All water parameters are very stable and within perfect ranges. Corals are fed 2x per week with Oyster Feast, Cyclopeeze, and Mysis, so I don't think water conditions or feeding are part of the problem.
I'm wondering how much new, individual electronic/digital ballasts (Ice Cap or other) will help, if at all.
My other option would be to add more T5s like this on the front and back of the Ocean Light to add 208 more watts of T5s: T5 Sun Beam dual high-output - Multiple wattage HQI bulb combination - Aqua Medic
This would give me nearly 7 watts per gallon. Radiums are not an option at this point.
