Matt Dyer –
I’ve used this pad in my 55-gallon tank for three months now. Water clarity has improved significantly, and my fish seem more active. Easy to cut and fits perfectly in my hang-on-back filter. No fish deaths or stress reported.
Sean Randall –
Works well in my canister filter. I cut it to fit the filter chamber and noticed nitrite levels dropping after a week. A little slower than expected, but still effective.
Lucas Mills –
Great product for maintaining stable water chemistry. I use it in both my freshwater aquarium and pond. The bacteria seem to work consistently without needing frequent replacement.
Neil Blake –
It works, but I had to cut it twice to get it to fit properly. The pad doesn’t seem to absorb as much as I expected, so I might need to replace it more often.
