Webb's Water Gardens Natural Phosphate Binder

This natural powder formulation produces a non-chemical alternative to using aluminum sulfate (ALUM) in koi ponds and water gardens. It contains approximately 70 trace minerals which work naturally to bind soluble phosphorous in pond water. It also buffers pH, which helps promote fish health and prevents drastic pH "swings."
