Good photo period for planted Fluval Spec?
I have a Fluval Spec II 2.6 gallon planted with java moss, java fern, and dwarf hairgrass. It's got about 1.5 - 2 inches of Fluval Stratum substrate. I have an outbreak of black beard algae that rode in on the java moss from the fish store. The tank has been fully cycled with a beta who eventually jumped out while I was asleep. Since there is currently no livestock in the tank, I was using that to my advantage and purposefully overdosing Flourish Excel which is killing the black beard algae (and the plants are actually doing great).
My real question though: what is a good photo period for the stock light on the Fluval Spec? I don't want to encourage algae growth and since I don't have CO2 I'm worried about giving the tank too much light.
