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

Excellent product which met all needs

Like the filters, great quality.

Not much to say, theyre good filters.

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

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

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

Replace filter once a month and I’ve had no issues with my 29 gallon tank. Have 5 snails to keep the algae growth down too. Minimal tank cleaning needed, just the monthly water swap and stone vacuum.

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

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

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
