Big Brand Leisure is a swimming pool supply store at 48 Porana Rd in Wairau Valley, on Auckland's North Shore. It has a 5.0 rating on Google.
A good pool supply store helps you keep the water safe, clear and easy to look after, and is happy to test a sample for you. Bring a water sample in a clean bottle, as staff can check chlorine, pH and alkalinity and explain what to adjust and in what order. Basic chemicals, test kits, cleaning gear, filters and covers are the usual stock, and covers cut both evaporation and debris. When choosing a supplier, ask whether they can advise on your pool type, whether it is chlorine, salt or something else, and whether they can order parts they do not have on the shelf. Regulars know that checking the water weekly through summer is much easier than fixing a green pool, and that chemicals should be stored cool, dry and away from children.
For pool owners on the North Shore, Big Brand Leisure on Porana Road is a local place to ask for advice and supplies.
