Jack Jones –
I’ve used Pristine for three months in my 55-gallon freshwater tank. The sludge at the bottom has significantly reduced, and water clarity has improved. The bacteria seem to establish well over time. No fish stress or changes in behavior noticed. Great for maintaining a clean tank without chemicals.

The bonus size is a nice addition — I got 30% more than expected. It works well in my marine tank. I see less detritus buildup and the water feels cleaner after a few weeks. A reliable, natural solution for water quality.

After adding Pristine regularly, my tank has had fewer algae outbreaks. The bacteria seem to thrive and break down waste efficiently. I appreciate the environmental initiative behind the donation to rhino preserves.
