Irene Slater –
I added a combination of ceramic and bio-balls to this cartridge and noticed a significant improvement in water clarity. The filter runs smoothly and the media stays in place well. Works perfectly with my 30-liter tank.
Thomas Sharp –
The cartridge fits exactly where the foam used to go. I replaced the foam with this and added sponge and activated carbon. My tank has better biological filtration now. Easy to install.
Bella Ross –
Great flexibility for customizing the filter. I used it with a combination of zeolite and sponge. The filter performs better than before and maintains water quality over time.
