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

Exactly how description indicated

Our filters are great. Easy to remove and insert. We can buy in bulk and save (even better!)

These filters are amazing and perfect I’m glad I found them on amazon because some pet stores sell these filters for outrages prices.

Not sure if these are original or just poorer quality, but they were of weird color, super dusty from the charcoal, and the spongy part was a bit too firm from what I’d consider their usual product. Either way, it’s ok value for the money, hence 3 stars.

as always, just fine

nice to have plenty of spares.

Excellent product which met all needs

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

A+++

they work but the boxes came covered in dirt and charcoal. not sure why that was.
