Betta tank filtered vs non filtered
I have a 10 gallon betta tank decently planted. I mainly bought a whisper 10i filter just to promote oxygen in the tank by keeping the water moving. Today I decide to clean the cartridge a little with old tank water since it looked like it had a lot of algae on it. The rest of the tank has no algae.
Well my question is since my cartridge came apart and I won't have one for a while is it even worth putting one in?? I hear activated carbon helps keeps the water clear. It's only a betta fish I've done water test and everything stays pegged at 0.
