Filters for bare bottom tanks
Posted: Thu Sep 29, 2005 9:30 pm
I saw that there were no posts in this section...so I thought I'd give it a shot. These are my home made filters for bare bottom tanks. They are mechanical and biological filtration, and cost about $3 to make. The filter media (not shown) is red flint gravel...which is used by Shedd Aquarium here in Chicago, as well as the city of Milwaukee, Wisconsin - for thier drinking water. The filters are called pot filters, and are made of a round undergravel (made by Lee's)/ a pot (I use old margerine containers or a plastic milk jug cut down to size)/ and red flint gravel for the filter media. I've had a few of these filters the entire 37 years I've been keeping fish. Although I'm new to keeping plecos (except for bristlenose), I've had 24 zebra spawns in the last 12 months! I've also bred close to 100 species of cories...using these filters.
The pics show aerobic growth on the filter plate, and the pot itself. In a few tanks, I even have the same aerobic growth on the glass. My friends at Planet Catfish IDed the particular type of aerobic growth for me...but I'd have to look it up.

If you have any questions...ask away! I'm a breeder, not a scientist. So anticipate common sense answers.
