I have a small blackbeard algae problem in my tank. It's not out of control, but I think the algae looks pretty healthy and im thinking its because my CO2 solenoid turns the CO2 off at night and the CO2 gasses off. Its takes the full 9 hours of CO2 on for plants to start pearling, so I think the fluctuation might be big enough to cause the BBA to grow. Would it be smart to put the CO2 on the whole time? Will this hurt my fish? My drop checker is kind of useless. I was thinking if the CO2 never fluctuated, the BBA would die off completley.
