I have a 3 gallon tank that originally had a betta in it (he's been moved to a 10 gallon) and I'd like to convert it to a planted tank before restocking it with fish. There's a lot of advice for larger planted tanks, but the advice on 3 gallons is pretty scant, so I have a few questions. How strong does the light need to be? Do I need to add any CO2? What plants would work best (I'd like to heavily plant)?
NOTE: the tank is the 3.5 gallon betta flo from TopFin. The lights stopped working so I'm replacing the hood and the filter takes up a lot of room so I'm going to try to find something smaller.
