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

Great

Works well

In this last shipment, the carbon had shaken out of the filters and was all over the inside of the shipping box. Usually thats not an issue. Kinda messy.

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!!

Great value

My fish are happy so I am Happy! Thank you

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.

Excellent for Aquariums

These are all standard products function as expected

good
