[quote="BL1, post: 547481"]That's definitely too long, you only want your lights to run 8-12 hours a day. If you want your tank to be lit later then you can start it later. When I ran my tank I had the lights come on at 11am and went out at 11pm so I could enjoy the tank for a while after I got home from work.[/quote]\n \n \nthat sounds great and thanks for the advice! Does my color plan sound right? blues, then blues and whites, then just blues again before blackout?
