, I use all 3 bulbs for 6 hours
Wow, I've got 11 watt over a 30cm cube and have some green spot algae and, for the first time, staghorn algae. And that was with co2 at 1bps! I've decided to take the co2 off the tank and run low tech to breed yet more shrimp. The shrimp may have bred with co2 but not taking the risk. It did take a while for the algae to appear though so you may be in for some after all...
