Blue Horizons Rapid Dissolving Chlorine Stabiliser prevents chlorine loss to sunlight. This is especially useful where an unstabilised chlorine product is being used. Usually added to pool water on first fill, or on emptying and refilling,or when substantial fresh water has been added after backwashing or heavy rainfall.
Cyanuric Acid acts as a “stabiliser” that helps chlorine hold up better when exposed to the UV rays associated with outdoors pools. The sun’s ultraviolet (UV) rays will make the chlorine in an outdoor pool dissipate quickly. In fact, an ideal level of chlorine in an “un-stabilised” pool or spa can be lost in less than two hours on a bright sunny day, due to UV rays of sun.
Cyanuric acid acts as a “stabiliser” that helps chlorine hold up better when exposed to UV rays. You can think of cyanuric acid as blocking the effect that the sunlight has on breaking down the chlorine – like sunscreen for your pool.
You should maintain an ideal level of cyanuric acis, 30-50 ppm (mg/l), to prevent rapid chlorine loss. If the cyanuric acid level is too low, you may need to add more to the water. However, be advised that cyanuric acid will make the pH of the water lower (more acidic), so you may have to adjust the pH upwards as well.
On the other hand, too much cyanuric acid will reduce the beneficial effect of your chlorine leading to stains or cloudy water. Some chlorine compounds already contain an amount of cyanuric acid. If you are using dichlor or trichor as your primary chlorine sanitiser, you are already introducing cyanuric acid along with the chlorine. If the cyanuric acid level in your pool or spa is too high, you will need to partially drain and refill with fresh water.
When you first fill your pool or spa, test the cyanuric acid level until you have added enough to reach the ideal range. After that test the cyanuric acid level a minimum of once a month throughout the pool season, If you are using dichlor or trichlor you will need to test for cyanuric acid more frequently to ensure that the level has not exceeded the upperlimit.
