When my pool goes green what should I do? You need to avoid your pool going green. Keep adequate chlorine in your pool, keep the water balanced and filter your water for the required time and you should never have to visit this problem. Most importantly you must act quickly. Pools do not go green overnight, although sometimes it may appear that they have. Our advice -run as fast as you can to your Pool Professional. Millions of Algae spores, too tiny to see, have been multiplying rapidly until there are so many that you can actually see them. As they continue to multiply the pool water gets greener and greener. Take a sample of pool water to your Pool Professional who will test the water and give you instructions on how to fix it. They will also ask you how green your pool water is. For example can you see the bottom? They also need to know how much water is in the pool, what is the interior of the pool, what brand and type of filtration you have, the brand and horsepower of your pump. If it is a salt pool the brand and model of your chlorinator. How green is it? Can you see the bottom? Remember it has taken some time to get to this stage so it may not get fixed overnight either. Do not allow swimmers in the pool until it is returned to its correct sanitary condition. The pool will need to be 'bombed' (this means heaps of chlorine), depending on the size of your pool with at least 20L of Liquid Chlorine and circulated to kill the algae spores. Your Pool Professional will advise you what dosage is required. You will need to clean your filter several times throughout the clean- up process. Once the algae spores die you will see it as a white/bleached cloud. The residue will need to be brushed from the pool surface so it can be removed by the filtration process or vacuumed out, leaving the pool clean and clear. The pool may need to be flocked using Floc (Aluminium Sulphate) which is a coagulant that causes the particles to drop to the bottom of the pool so they can be then vacuumed to waste. 34
