Austin Roberts –
Used AlgaeFix in my 500-gallon pond during summer. The water cleared up within 3 days. No fish or plants were affected. Works well for green water and hair algae. Aeration was running consistently, which helped maintain water clarity.
Leonard Powell –
Good product for controlling string algae in my fountain. Took about a week to see results. I didn’t notice any fish stress. Only used it once a month after initial treatment.
Andrea Young –
Felt like a real solution after months of algae issues. The water became noticeably clearer within a week. No side effects on my koi or water lilies. Easy to measure and apply.
