Super Easy to replace

I wish they are were a little less expensive.

Well made and worth the money

Works

I like how clean it keeps my aquarium

I had trouble finding these filters at the pet store. So many different types on the shelf. It’s nice to just plug in the filter name, order online, and receive in 2 days. Perfect fit for our beta fish tank.
