Bio Rings

There are a lot of bio rings you get for this price. Best value I could find.

They come in a net too which is all inside a plasic bag so you don't get dust all over the place during shipping.


bought these bio ring for m hang on back filter. they fit just perfectly. I also loved how little waste was used in the package of the product, item was shipped with two other item. Also come in a really nice little baggy so they all stay together. Over all great product!

I recently added the rings to my HOB filter as well as a sponge cover for the intake. The water tests well and remains clean. Im in the process of adding them to another NOB filter

A Sump Must

I was inspired after watching Cory build the sump for the 800gal, to build one for my 100gal pleco tank. I have never worked with bio rings before, and I can't believe what I have been missing! They offer so much surface area, constructed very well, and come in a sturdy bag! They keep the water polished clean and I love knowing my tank is overall healthier! Shipping was Amazon Prime fast, and although my box looked like it had been chucked off a building, the bio rings were all intact! Love this addition to my sump and will definitely be ordering more in the future!

I saw Cory’s YouTube video on how to hot rod your hang on the back filter. I added bio rings, a bigger corse sponge, and a fine flossing filter. The system is working great. The shipment arrived quickly. In fact, I have a shipment of other goodies in transit right now from Aquarium Co-Op!
