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

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

As advertised.

Not much to say, theyre good filters.

nice to have plenty of spares.

These filters are great! Works like company says.

Like the filters, great quality.

as always, just fine

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

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.
