I have a 2 10gallon tanks each have 3 filters on them a aquaclear20 a whisper10 and a sponge filter for up to 25g. My question is are all my filters actually helping my tank adequately or is it just overkill and 3 would be as good as just one sponge filter? My tanks are all well planted as well and I do regulat water changes just wanna hear everyone's thoughts on using multiple filters or different kinds of filters together to get all the benefits from each
