So I've put a Eheim Mini Flat filter in my set up on it's lowest setting and since doing so my toads don't seem to be in the water as much. When I've been reading up online some people advise strongly on the use one to maintain water quality and others are against it because they're afraid of it disturbing the toads. Just wondering if you guys filter or not and your thoughts on this and if you think I should leave the filter in or take it out.
