Michael Piper –
I’ve used these pearls in my 55-gallon freshwater tank for three months. The water clarity has improved noticeably, and I see less algae growth. The setup was simple and the pearls didn’t break apart during use.
Jane King –
The pearls work well with my filter system. I noticed a drop in nitrate levels after two weeks. No clumping or clogging issues. A reliable addition to my aquarium maintenance routine.

After switching from a chemical filter to this bio-media, my tank has stayed stable with fewer water changes. The PHA material seems to support a healthy bacterial colony over time.
