The filter cartridges work well in my 20-gallon tank. The water clears up faster than before, and the smell is much less noticeable. Easy to install and the dense floss holds up well after a few weeks of use.
Diana Stewart –
I’ve used these for about a month now and notice a significant improvement in water clarity. The activated carbon seems to be effective, though I’d prefer a slightly longer filter life.
Bernadette Black –
Great product for maintaining a clean tank. The large size fits perfectly in my filter and the carbon filtration is noticeable after just a few days of use.
