Water TechniX Black Spot Algae Remover – Powerful Algae Control for Pools

Water TechniX Black Spot Algae Remover is a premium, slow-dissolving, high-strength treatment designed to eliminate black spot algae and keep your pool crystal clear. Perfect for treating widespread or difficult-to-spot algae, this product helps you maintain a clean and healthy pool year-round.
💡 Did You Know Black spot algae's root cause is usually a lack of sanitisation (chlorine). If black spot keeps appearing, check that your chlorine levels are balanced (usually 2-4 ppm for residential pools). If your chlorine level is consistently under, your chlorinator, salt levels or salt cell may need assessing to ensure enough chlorine is being dosed.
