I am wondering how long it is going to take to get the algae levels to cover the rocks and tanks? I give it about 12 hours of flourescent and regular lighting a day, but I think I need to try to keep the water temp more consistent because the ambient tempratures in the room can drop at night ultimately effecting my water. Should I get a beta heater? I am good with water changes, so that should help. What is the secret of keeping mini reefs alive and dwelling?
