🔋 Convenient 12-Pack Marineland Rite-Size C Cartridge Refills: Guaranteed Efficiency Review

These are good filters, I just want you to not buy twelve packs for $27, they only send you 2 packs of six packs, so it's better plain Buy 2 packs of six at $6 each and pay half the price for the same number of filters.

I use the larger Marineland filter on my 20 gallon tank. Two filters are required. This replacement was perfect as pet stores have mostly been closed during the pandemic. Arrived quickly and exactly what I needed. I didn't understand Revain's "easy to clean" rating as you don't clean them. You replace them when they get dirty. Thanks to the filters, my aquarium really shines between cleanings. I'm a fan!

Great product but I've never seen so much charcoal on the bottom of a package. There are many slits in the filter, the water can flow straight and won't touch the charcoal. I don't know how effective they will be. But after spending so much money I was very disappointed with the quality of the filters, I use two at a time and how it will be better for the fish.

This rear mount marine filter is great value for money! It provides mechanical and biological filtration and offers space for up to 4 filter mats. Biowheels provide water filtration and movement in an almost silent mode. I hesitated a little, thinking it would be a noisy filter, but it turned out to be the quietest filter I've ever had. It only takes up 3 inches of clear space from the wall and it's like having 2 filters instead of one.
