6-Pack, Size B, Rite-Size Cartridge Refills

Satisfied. Used many years

These filter well, but I wish they were more environmentally friendly. They would be more efficient if I could clean them for reuse. They leave black specks on the fabric which sometimes get into the tank. They do a good job cleaning the tank.

About the only kind available. Soooo

It’s a great product, I’ll keep buying for my tank but Last two times I’ve gotten it from Amazon the box comes crushed and one of the filters are broken I would have sent it back I needed to change my water in my tank.

Available

They work fine! Best to get when on for a good price!

Love the filters

good

JUST WHAT I NEEDED

I had another pump that didn’t work as well as I needed it to. I purchased the Marineland pump and these are the perfect replacement filters. The original brand and a better price than the pet stores. Thanks Amazon for a great deal. I will purchase again.
