Used this in my koi pond for the first time last month. The green water started clearing up within a week. My plants look healthier and the water feels more balanced. No fish stress or plant damage noticed. Good value for the algae control.

Felt like a real improvement over chemical treatments. The algae didn’t come back as quickly after use. My pond is cleaner and the oxygen level seems better. Works well with my existing plants and fish.
