I know these things are poop machines lol but how often should you vac with them i have a pleco and a tiger oscar in a 55 gallon for now the oscar is still fairly small and he will be moving once i get a new tank. But my question is how often should i gravel vac i do wc's atleast 3 times a week if not more on some occasions but it seems like even if i gravel vac every day there is just a ton of poo on the substrate. Although i don't mind graveling sometimes i just don't have the time since i am up with my 6 month old pretty much 18hrs of the day although she sleeps most of the time i know i am lucky lol. And also isn't BB suppose to help somewhat with the breaking down of the poo and everything i was just curious as i like my tank to look fairly clean most of the time i have no water clarity issues or anything but i was just wondering if i shouldn't stress about it and just go with it or what im just curious lol.
