lighting times?

[pgr11]

Any suggestions on setting up my lights on a timer. How long should they be on? should 1 set be on longer than the others? I have t5 4 bulb set up. Just wondering where to begin

Around 8 hours should be good. Any more will give you algae problems. I have mine on from around 2pm to 9:30pm.
