I recently tried this thread on AC. Apparently there are no ACers that want to think outside of the box. I aquired a small pool filter and it's been sitting around in my garden shed. Lately I have been interested in Vortex diatom filters. I want to use the pool filter as a diatom and as a maintenance routine to polish the water column. I wonder if anyone on MFK has used a pool filter in their aquarium.
