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

Exactly how description indicated

Not much to say, theyre good filters.

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.

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.

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.

A+++

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

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

As advertised.

nice to have plenty of spares.
