:confused: Hi guys, Trying to get to grips with planted tank.
How long should my lights be on for in my planted tank??
1 x 48" T8 Classica Tropical Sunlight
1 x 48" T8 Classica Natural Daylight

Tank = 54" L x 12" W x 18" H
About 50 US gallons
 
I'm assuming that your t8s are 40 watts apiece? If this is the case, you can probably go with about 9-10 hours. What sort of plants do you have?
 
So you're right about 1.5 wpg. Here's a good link to identify plants and browse what might be appropriate. I think the 9-10 hour range should be a good starting place though. You can adjust from there depending on the results.
