Used AQUA GUARD PSB in my 100-liter freshwater tank for three weeks. Water clarity improved noticeably and I saw less algae buildup. My fish seem more active and the tank feels more balanced. Easy to mix and no side effects observed.

Good product for maintaining water quality. I added it every two weeks and noticed a steady improvement in oxygen levels. Works well with my planted tank. Slight delay in visible results, but consistent over time.

After switching from chemical water treatments, I started using AQUA GUARD PSB. The tank has become much cleaner and the plants are thriving. No fish stress or changes in behavior. Highly recommend for natural water balance.
