is my light cycle causing algae/diatoms?

Just wanted a few opinions on this.



I have an odyssea t5 ho light fixture with timers.



i run 2 white bulbs from 8am-8pm

a blue and white bulb 11am-5pm

then at 8pm-midnight the moonlight LED lights are on.



lately i have been keeping the lights off most of the day to see if that helps.



the tank is a 75 gallon and no corals. live rock with fish.



any suggestions?
