ADFs and Tank Filters?
So after my last post, my frogs have upgraded their lifestyle quite a bit and seem happy. I have one new question though.
I've read mixed things on the internet about filters and water movers (I'm sure there's a proper term, I mean the things that don't actually remove anything from the water, they just create a current at the top) and ADFs. Some sites have said some sort of current is needed to keep algae from growing, others have said ADFs get stressed out by having a current.
Are my frogs okay in their new tank with no current and no filter whatsoever? I change 50% of the water once a week and have a gravel vacuum, is that enough to keep the water stable and clean?
