OASE Lake Therapy SeDox Phosphorus Binder 50 lb

OASE Lake Therapy SeDox is a mineral-based phosphorus binder that addresses eutrophication — the slow decline of water quality from nutrient loading — by permanently removing phosphate from the water column. Through the natural formation of apatite, SeDox eliminates phosphorus as a nutrient source while simultaneously releasing oxygen and balancing pH. Each 50 lb bag binds approximately 1 lb of phosphate.

What It Treats

• Excess phosphorus and nutrient loading in lakes and ponds
• Algal blooms fueled by free phosphate
• Early and advanced stages of eutrophication
• Low dissolved oxygen tied to nutrient overload

How To Apply

• Dry or slurry application (slurry is preferred for even distribution)
• Apply evenly across the water surface of the body of water
• Treatment rate: 50 lbs binds ~1 lb of phosphate — match dose to measured phosphate load
• Repeat as needed based on water testing; effects are long-lasting per application

Key Features

• Permanent phosphate binding — apatite formation locks phosphate away as an inert mineral
• Releases oxygen as it reacts, helping balance pH and benefit aquatic life
• No heavy metals, no aluminum, no residue — mineral-based and safe for fish and wildlife
• Commercial-grade — used by lake management professionals for restoring fisheries and recreational ponds
• Alternative to alum — avoids aluminum buildup and pH crashes associated with traditional alum treatments

✅ Safe for fish, wildlife, and aquatic plants. Leaves no residues or inert materials behind.
