I used this after adding new fish and noticed a significant improvement in water clarity within a week. The bacteria seem to work well with my filter system and help break down waste naturally.

Works well after filter cleaning. I add it every few weeks when I see detritus buildup. My tank feels more stable now with fewer water changes.
