Irene Buckland –
I’ve used Pristine for three months in my 100-gallon freshwater tank. The water clarity has improved noticeably, and I see less sludge buildup. The bacteria seem to establish well and work steadily without any side effects. Easy to mix and apply once a week.
Steven Allan –
It took a few weeks for the bacteria to fully establish, but after that, my tank has much cleaner water. I noticed a reduction in algae growth and less fish waste accumulation. Works well with my regular water changes.
Caroline Hardacre –
After switching from a chemical filter cleaner, I found Pristine to be a much more natural and effective solution. My tank feels more balanced, and the water stays clearer longer. No fish stress or changes in behavior observed.
