Best pool test kits

If your above ground pool has turned into a green, murky swamp, don’t panic—it’s a common issue caused by algae, debris, and chemical imbalances. Above ground pool maintenance starts with identifying the problem: green pool water usually means algae (green, yellow, or black) has taken over, while cloudy water signals poor filtration or pH issues. To fix green pool water, shock the pool with 2-3x the normal chlorine dose, scrub the walls with a stiff brush, and run the filter non-stop for 24+ hours. For stubborn cases, an above ground swimming pool cleaning service can handle the heavy lifting with industrial-grade treatments. Preventing pool algae requires weekly brushing, proper pool chemical balance (chlorine 2-4 ppm, pH 7.4-7.6), and regular filter cleaning for pools (backwash sand filters, soak cartridges). DIY pool care includes skimming daily, shocking monthly, and testing water twice a week with one of the best pool test kits (liquid kits beat strips). If algae keeps returning or your filter struggles, it’s time to call above ground pool cleaning services—they’ll deep-clean, optimize equipment, and save you from endless scrubbing. Whether you tackle it yourself or hire a swimming pool cleaning service, consistency is key to keeping your water crystal clear.
