Used AQUA GUARD PSB in my 100-liter freshwater tank for two months. Water clarity improved noticeably, and I saw less algae growth. The bacteria seem to work well with my filter system. Easy to mix and no fish stress reported.
Justin Hill –
Added it during a water change after a fish die-off. The tank became clearer within a week. I don’t see any fish behavior changes. Would recommend for maintenance routines.

It worked in the short term, but I didn’t see long-term results after three months. Maybe needs to be used more consistently or combined with other treatments.
