💧 How to Use PHOSfree Max to Remove High Phosphate Levels

PHOSfree Max is a powerful and fast-acting solution designed to eliminate high levels of phosphates from residential and commercial pools. High phosphate levels can contribute to algae growth, poor water quality, and scale formation — all of which make pool maintenance more difficult. This treatment brings phosphate levels down to near zero in as little as 24–48 hours, making it a great option for seasonal cleanups or stubborn algae issues.

🧪 Recommended Dosage

• 1 quart (32 oz) per 20,000 gallons of pool water

• For pools under 10,000 gallons, do not exceed 16 oz per treatment

⚙️ Step-by-Step Instructions for High Phosphate Treatment

Step 1: Clean or Backwash the Filter

Before starting, clean or backwash your pool filter to ensure optimal flow and performance during treatment.

Step 2: Calculate and Add Product

• Measure the correct amount of PHOSfree Max based on your pool volume.

• With the pump running, pour the product directly into the pool, distributing it as widely as possible across the surface.

💡 Important: Cloudy water after treatment is normal — it means the product is actively removing phosphates.

Step 3: Run the Filter for 24 Hours

Let your filtration system run continuously for at least 24 hours to allow PHOSfree Max to fully circulate and do its job.

⚠️ Do not swim while the pool is cloudy — plan your treatment accordingly.

Step 4: Monitor Filter Pressure

• Keep an eye on your filter pressure gauge.

• If pressure rises 10 PSI above normal, stop and clean or backwash the filter again to prevent flow issues.

Step 5: Retest After 48 Hours

• After 48 hours, test your phosphate levels using a phosphate test kit designed for swimming pools.

• If phosphate levels remain high, repeat the treatment as needed using the same dosage guidelines.

💡 Why Use PHOSfree Max?
