Guides for your pool

• Above-ground pool maintenance: the typical week, without the fuss — How many hours to run the pump, how often to clean the cartridge, when to test chlorine and pH, which products to use. The simple routine for Intex, Bestway and similar pools.
• Chlorine in range but green water? It's probably the stabiliser (cyanuric acid) — If you use tablets all summer, the stabiliser builds up and locks the chlorine. How to spot it, what level to aim for and how much water to replace to fix it.
• Green pool water: what to do tonight (and why chlorine alone isn't enough) — Green pool? The step-by-step procedure: pH to 7.2, check the stabiliser, shock with the right doses. Works for Intex and Bestway pools too.
• High pH in the pool: how to lower it without overdoing it — pH above 7.8? How much pH minus to add per 10 m³, why it should be done in small steps, the role of alkalinity and what to do if the pH keeps rising.
• How much chlorine to add to a pool: doses per cubic metre, product by product — Grams and millilitres of chlorine per cubic metre: dichlor, trichlor tablets, liquid chlorine, calcium chlorine. With the right level to keep based on the stabiliser.
• How many litres does my pool hold? Intex and Bestway table and how to work out the volume — Litres of the best-selling Intex and Bestway above-ground pools, and the formulas to work out the volume of round, rectangular and oval pools. The number every dose needs.
• What to buy for your pool: the minimum kit, product by product, no brands — Which chlorine to choose, what you really need for pH and alkalinity, which test strips to buy and what to read on the label. The kit for an above-ground and an in-ground pool, with price ranges.
