Instructions

Treatment Dose:
Use the dosage chart below to determine how much SeaKlear PhosKlear 4000 to add based on your pool size and current phosphate level. For example, a 10,000 gallon pool with 1,000 ppb of phosphates should be treated with 8 oz of product.

Dosage Chart

Initial Phosphate Treatment:
Clean or backwash the filter before starting. Use the chart above to measure the correct amount of product. Pour the PhosKlear 4000 evenly across the pool surface. If the water is still cloudy after 24 hours, apply SeaKlear Chitosan Clarifier at 2 oz per 5,000 gallons. Run the filtration system continuously for at least 24 hours. If the filter pressure rises 10 psi above normal, clean or backwash the filter. After 48 hours, test phosphate levels with a swimming pool phosphate test kit and reapply product if needed.

Weekly Dose:
Add 2 oz of SeaKlear PhosKlear 4000 per 10,000 gallons weekly to help maintain low phosphate levels and keep the water clear.

Important:
Temporary cloudiness is normal while phosphates are being removed. The water may stay hazy for up to 24 hours depending on phosphate levels and filtration performance. Swimming should be avoided until the water clears. If desired, use SeaKlear Chitosan Clarifier at 2 oz per 5,000 gallons to speed up water clarity.

How can I tell if my pool needs PhosKlear 4000?

If you have recurring algae, cloudy water, or phosphate test readings above 500 ppb, PhosKlear 4000 is typically recommended. Customers often bring water samples into DPM for testing to verify exactly how much remover is needed.

Is this the right option for sudden phosphate spikes?

Yes — this concentrated formula is ideal for pools with high phosphate levels that need fast removal. Staff can help calculate dosage in store based on your gallonage.

Will this product work with my existing sanitizer?

Yes, PhosKlear 4000 is compatible with chlorine, salt, mineral, and alternative systems and won’t interfere with standard sanitizers.

Applying the Product, Behavior in Water & Filter Expectations

These questions explain how PhosKlear 4000 works once added to the pool.

Does the water cloud up after adding phosphate remover?

A slight haze can appear temporarily as phosphates bind and get filtered out. Running the pump continuously and cleaning the filter after treatment speeds up clearing.

Where should I pour the product for best results?

Pour it around the pool perimeter or directly in front of a return while the pump is running. Avoid pouring into the skimmer with a cartridge system to reduce filter loading.

How long does it take to see improvement?

Most pools show clarity improvement within 12–48 hours depending on phosphate levels and filter condition.

In-Store Pickup, Troubleshooting & Treatment Planning

These questions help customers prepare for their visit to Discount Pool Mart.

Is PhosKlear 4000 usually available for same-day pickup?

Yes — DPM locations regularly stock SeaKlear products, especially during algae season. Calling ahead with the SKU ensures availability.

Should I retest my water after treatment?

Yes, retesting confirms phosphate reduction and helps determine whether a follow-up dose is needed.

Should I buy backup filter elements or cleaner?

Removing phosphates generates extra filter debris. If your filter is old or overdue for cleaning, purchasing cleaner or media during your visit may help improve results.
