The only filters I use for my 5-Gallon Hex tank.
October 19, 2014
I constantly use these for my fish tank. They make my 5-Gallon Hex look crystal clear month after month, replacing them once a month. I tried using regular foam blocks a while back, but they did little to nothing for my tank. Switched back to official Marineland filters and will never go back to anything else. Highly recommended!
ProsEasy and simple to install.
Makes my 5-Gallon tank crystal clear, like new.
Pricing is fair.
