Its lanthanum-based formulation binds phosphates rapidly and allows them to be captured in the filtration system, providing clearer, more stable water with minimal product use. Suitable for routine upkeep or targeted treatment of high phosphate spikes, it supports better sanitizer performance and contributes to cleaner, healthier pool conditions. The formula can be applied directly to the water and is compatible with chlorine, saltwater, mineral, and UV systems as well as all pool surfaces. Its concentrated strength ensures dependable results for both service professionals and informed pool owners.\u003c\/p\u003e\n\u003ch3 data-start=\"3197\" data-end=\"3215\"\u003e\u003cstrong data-start=\"3201\" data-end=\"3215\"\u003eHighlights\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cul data-start=\"3216\" data-end=\"3946\"\u003e\n\u003cli data-start=\"3216\" data-end=\"3364\"\u003e\n\u003cp data-start=\"3218\" data-end=\"3364\"\u003e\u003cstrong data-start=\"3218\" data-end=\"3255\"\u003eConcentrated Phosphate Reduction:\u003c\/strong\u003e Formulated to eliminate elevated phosphates quickly, helping limit algae growth and improve water balance.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3365\" data-end=\"3514\"\u003e\n\u003cp data-start=\"3367\" data-end=\"3514\"\u003e\u003cstrong data-start=\"3367\" data-end=\"3395\"\u003eLanthanum-Based Binding:\u003c\/strong\u003e Uses lanthanum to pull phosphates out of solution and into the filter for removal without heavy clouding or residue.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3515\" data-end=\"3657\"\u003e\n\u003cp data-start=\"3517\" data-end=\"3657\"\u003e\u003cstrong data-start=\"3517\" data-end=\"3549\"\u003eBoosts Sanitizer Efficiency:\u003c\/strong\u003e Helps chlorine and other sanitizers work more effectively by reducing nutrient levels that support algae.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3658\" data-end=\"3808\"\u003e\n\u003cp data-start=\"3660\" data-end=\"3808\"\u003e\u003cstrong data-start=\"3660\" data-end=\"3693\"\u003eVersatile Pool Compatibility:\u003c\/strong\u003e Safe for use in all common sanitizing systems and on all pool surfaces including plaster, vinyl, and fiberglass.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"3809\" data-end=\"3946\"\u003e\n\u003cp data-start=\"3811\" data-end=\"3946\"\u003e\u003cstrong data-start=\"3811\" data-end=\"3839\"\u003eThirty-Two Ounce Bottle:\u003c\/strong\u003e Provides enough product for routine maintenance cycles or concentrated treatment of high phosphate events.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstructions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eTreatment Dose:\u003c\/strong\u003e\u003cbr\u003e\nUse the dosage chart below to determine how much SeaKlear PhosKlear 4000 to add based on your pool size and current phosphate level.

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.
