What brand canister filter would be best to filter a 110 gallon indoor pond? I am on a budget so I would like something rather cheap. The inhabitants will be 1 oscar, 1 gold jack dempsey, 5 convicts, 1 common pleco, and 1 mystus leucophasis. Also would I be able to fit 3-5 silver dollars in there? The pond is an oval shape and has a pretty large footprint. Thanks ahead.
