Those are reallyyy pretty girls! =] I've started out the tank. Just letting the filter run and the lights (on a schedule). I tried leaving the lights on part of the time and turning them off part of the time, but lots of icky brown algae got on this one plant... So, we left the lights on more.. Now, there's green algae, too. -_- And the brown algae is still there!!!
The more you have the lights on the more algae will appear. lol I'd just leave the lights off completely until it's been cycled. Once you have the fish in there turn one the lights for about 8-10 hours a day.
Good Luck! :D
