Biostim PhosFix is a powerful, proprietary blend of minerals and beneficial bacteria developed to remove phosphorus and reduce organic turbidity in ponds, dams, and lakes. Ideal for maintaining clean, balanced water in both natural and constructed water bodies, Biostim PhosFix delivers fast, effective results without harming aquatic life.
Whether you manage a farm dam, private lake, ornamental pond, or water feature, Biostim PhosFix offers an eco-friendly and efficient way to manage excess nutrients and restore water clarity.
How Biostim PhosFix Works
Biostim PhosFix is a combined probiotic and phosphorus-binding flocculant that begins working within hours of application. It targets excess phosphorus, a key driver of algae blooms and eutrophication, and binds it into the sediment where it becomes inactive. At moderate doses, Biostim PhosFix binds phosphorus in the water column, but at higher doses, it is able to lock up phosphorus bound in sediment as well as in the water column.

Easy to Apply
Using Biostim PhosFix is simple; the goal is to spray the required amount over the entire surface of the water body.
