Marineland Rite-Size Cartridge Refills (18-Pack, C - Blue)

Not bad.

We have had great success with these filters using them in our Bio Wheels on both tanks. Economical way to purchase, always have a supply handy

These filters keep my aquarium clean and the fish happy...

I bought the wrong size. I need the “E” not “C” filter. I have opened one box to take out the filter, then realized the size was wrong, I passed the return date. I would like to exchange them for the size “E” filter. Thank you

Good price delivered as promised

This multi- pack of filter media for fish tanks is a good value and the product is high quality.

These filters are great! Works like company says.

nice to have plenty of spares.

Excellent product which met all needs

Using the manufacturers recommendation, also just by looking at the water quality, its obvious these filters are doing their job. My fish love it thank you
