I started dosing Liquid Carbon to this tank. Extra C is welcomed by plants and it does act as an algaecide against the BBA. So far no fish/snails are harmed by it. The most important thing with this kind of product is DO NOT OVERDOSE.
Journal about how I'm running and maintaining this 180 liters planted tropical fresh water aquarium. From day one till the end of time ;-) with all it's good and bad moments.
