I like biowheels, they do a great job converting ammonia to nitrate. I also use them to breed Tanganyikan killiefish, they like to lay their eggs in crevasses, and the folds in the filter work as a substitute just fine; place them on the bottom of the tank.

Easy to find
I check with other fish distributors and most did not carry placement part , but foster and smith did; thanks for caring spare parts it saved me a lot of money by that I mean did not have to but a total new filer unit.

Only thing we buy!
High quality and are so much more cost effective. The bulk discount is great and makes the price even better on the filters. We have had nothing but good experiences from these parts and Drs Foster and Smith.
