Tad - as far as the filter goes, i don't currently have a picture of it, but let me try to explain it to you and see if it makes sense; The pump has a 2" line that runs into the filter container, then there are 4 foam filters. The water is then pumped back out of the filter and up into the falls.
Does that help any?
Either i misunderstood you or vise-versa b/c i don't clean it twice a day, but about every 2 maybe 3 days at the most. And every time i pull the filters out they are covered with green algae.
