Benjamin Miller –
Used AlgaeFix in my 100-gallon pond during summer. The water cleared up within a week. No fish stress or plant damage. Works well with my existing aeration system.

Good results against green water algae. Applied once a week after measuring pond volume. Noticed improvement in water clarity after 5 days. Would recommend for small to medium ponds.
