Undergravel Filter
Otto Undergravel Filter - Easy to assemble for any common aquarium size. The plates in two or more kits can be connected together, enabling these filters to work in almost any size aquarium. Undergravel Filters have been recognized for many years as one of the best values in aquarium filtration. There are 3 plates in each kit, each 10.8" x 5.2" These plates do not include lift tubes. If needed, they must be ordered separately. Undergravel Filter Pads - These poly pads are stiffer than normal and make great additions to tanks with undergravel filters. Just place them over the plates, under the gravel. These increase biological filtration greatly over a regular setup with just gravel over the plate. Pack includes 3 pads 11.5" x 11.5". |
