Help with Lighting times

[revrick3]

I have a 90gl. with zoa's and couple soft coral along with fish. Lights set on timer and I have one 48 inch T-5 with total of 216 watts(2-10,000 and 2-18,000 bulbs), I also have a 48 inch PC with total of 260 watts( 2-10,000 and 2-actinic bulbs). I currently have timer set to keep lights on 12 hours day but am having trouble with algae. LFS told me to only run lights 9 hours day at most. They said to run all lights for 9 hours then turn them all off with exception of any LCD moon lights that might be on. Does this sound about right.

Address whats really causing the algae... overfeeding, lack of proper inorganic nitrate and phosphate export..
Do you already have a refugium or turf scrubber?

Have cut back on feeding, only a yellow tang and foxface in tank, feeding algae sheets every couple days with SMALL amount of pellets every other day. They go nuts when its feeding time. Have a refugium with live rock and chaeta in it, recently put a sock on water intake and microfilter. getting better it seems, still need help with lighting questions.
