How do I dose cyanuric acid and how do I test for it?
Cyanuric Acid comes in a granular form and unfortunately is very hard to dissolve due to its composition. This difficulty in dissolving Cyanuric Acid should not dissuade you from using it as it has a dramatic effect on reducing the chlorine consumption of your pool on a sunny day. The best way to dose it into a pool with skimmer boxes is to dissolve it in hot (not boiling) water and stir thoroughly. Mix no more than 0.5 kg of product with 8 litres of hot water in a 10 litre bucket. Once thoroughly mixed carefully and slowly pour the liquid solution into the skimmer. Be careful not to pour any undissolved chemical into the skimmer as it is very abrasive may damage the pump. Repeat the process until the required dose of chemical has been dissolved and dosed into the skimmer, remember this may take some time so be patient as the result is worth it. For a pool with a balance tank slug dose the product into the far side of the balance tank well away from the pump suction.
