Hello everyone,
I currently have a fluval U4 filter with two red eared silders in a 75 gallon tank; I already know I need a bigger tank but I cant get one right now cause of no room. However I do want a better filtering system.
So my question is; what is the best filtering system I can get without having to clean out the tank all the time? I don't care about the price but I do want it too be realistic, is it possible to set it up so I NEVER have too clean it or clean it like once every few months?
thanks
