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

My turtles water tank is always clear thanks to these filter replacements. Ive tried several brands and this one is by far the most reliable. Dont worry if you see some droplets around the box, its normal

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

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

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

nice to have plenty of spares.

as always, just fine

I have a 125 gallon and I have 2 of the marineland 350 filters on it and they keep the water crystal clear. Yeah Ill eventually upgrade to canister filter but these have worked great for well over a year so far , so why did whats not broken.

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

As advertised.

Used for a personal in-house tropical fish tank. Liked the price -buying in quanity saves extra trips to the store for purchase. All that have been used so far were in perfect condition. Will probably order again.
