The only ones voted even better looking by our visitors are our "Clear Top" bells that we also offer for a bit more money. Kids love watching them work as well. The only thing kids love more is watching the fish. We have built and shipped over 1000 bell siphons so buy with confidence. You get everything you see in the main photo including the 2 adjuster rings. A complete bell siphon ready to go in your 12" deep IBC media bed.
