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

This was a fair price for the exact filter I needed. I like the fact in came in a 6 pack, which will last me awhile. Thanks!

These fit perfectly and the price is great

JUST WHAT I NEEDED

Exactly as described. Works great for my 10 gallon tank, if I had a larger tank I would recommend investing in a slightly stronger irrigation system for optimal waste removal.

Buy these through Amazon because of value. Only issue is when receiving a lot of charcoal dust in package.

works in aqua-tech filters also

These are all standard products function as expected

Available

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.

The product is fine, does what its used for. My issue is the packaging. Instead of putting it in a box it was in a cheap paper bag! The box was crushed which crunched the filters and released some of the charcoal. VERY disappointed!!
