A must have
It rocks in my filstar canister filter.
by Lori Z
I have an oscar and plecostamos in a 55 gal that I could not control nitrates even with massive water changes. 2 pouches added to filter and recharged every week now has the nitrates down below 20. Would recommend for anyone with an overstocked tank. But use common sense and still do weekly water changes. This is not a replacement for water changes, but when that's not enough, this works great.
