Pool Cleaning Chemicals – Surface & Equipment Cleaners

Cloudy water, stubborn stains, and scale buildup can turn your backyard oasis into a frustrating chore. The right pool cleaning chemicals make all the difference between a pool that merely functions and one that sparkles. At PST Pool Supplies, you will find professional-grade clarifiers, stain removers, phosphate eliminators, and filter cleaners designed to restore water clarity, protect your equipment, and keep your pool looking its best all season long.

Water clarity starts at the molecular level. Our pool clarifier options — including Super Blue Clarifier, Blue 2000 Clarifier, and the AquaPill Clarifier Plus — work by coagulating microscopic particles that pass through your filter, binding them into larger clusters your filtration system can capture. For severe cloudiness, DuraChlor Flocculant settles suspended debris to the pool floor for quick vacuuming. If phosphates are feeding persistent algae growth, the Orenda Blue PRO10000 Phosphate Remover and Phosphate Away deliver targeted nutrient elimination that starves algae at its source. Foam appearing on your water surface is another common nuisance — our Anti-foam treatment eliminates it in minutes without disrupting water balance.

Metal staining and scale control are among the most overlooked aspects of pool maintenance, yet they cause some of the most costly damage. Iron, copper, and manganese dissolved in your fill water leave rust-colored or blue-green stains on pool surfaces, while calcium scale coats heater elements and clogs filter media. Our pool stain remover lineup tackles these problems head-on: Rust-N-Scale dissolves existing mineral deposits, Metal Wizard chelates dissolved metals before they can stain, and the Pro Series Stain & Scale Control (5-gallon) provides ongoing prevention for high-volume or commercial pools. The Spot Stain Remover Gel delivers precision treatment for localized discoloration without draining your pool. Natural Chemistry Pool First Aid uses enzyme-based formulas to break down non-living organic waste — sunscreen, body oils, and cosmetic residue — that dulls water and gunks up your filter.

Your filtration system deserves the same attention as your water. A dirty or clogged pool filter forces your pump to work harder, shortens equipment life, and reduces water turnover. Our Liquid Filter Cleaner strips away accumulated oils, scale, and debris from cartridge and DE filter elements, restoring flow rates and extending filter life between replacements. Cover Cleaner keeps your pool or spa cover free from mildew, dirt, and UV damage, preserving its protective seal.
