Was wondering if 6 t5 bulbs at 39 watts and 260 watts of pc lighting would be enough lighting to grow the corals which need the stronger light in a 90 gallon? Would appreciatte any feedback. Thanks Joe
joe, i'd sell the pc's and purchase 8 x 54 watt retros with individual reflectors. the trouble is the depth of your 90. the power compacts aren't the best for penetration.
