Marineland Ritefilter Cartridges

I have a few Marineland filters,so I purchase a couple different sizes of filter cartridges.
Can be pricey,if you don't shop around,but they do work well for what they are.
Rinsing them out occasionally will lengthen their life span.

Pros: easy to find comes in different sizes

Cons: none

These inserts survive and survive and survive. You can rinse these badboys out many, many, many times before the poly material starts to break down. The carbon will of course, be exhausted after the first month, but it's cheaper to rinse these and add carbon behind them in a used nylon or filter bag and these inserts rock!

Pros: high quality insert

Cons: pricier than most other brands
