I've been running all my tanks on 8 hours light.
Is this right? Are there any "golden rules" in regard to how long you should leave your lights on for best plant growth/algae prevention.
Currently i have -
43G corner planted tank with about 2 wpg
(HOT5's with reflectors).
20G tall with about 1 or less wpg
1G shrimp tank with 9 wpg
and weaping moss
