This Chemical compound which is supplied in both powder and granular form is commonly known as ‘stabiliser’ or ‘conditioner’.
It is used in swimming pool applications that are ‘unstable’ such as Liquid Hypochlorite (bleach) either as 14-15% or 10/11½%, Calcium Hypochlorite granules or tablets (approx 65–70%) and Lithium Hypochlorite granules (approx 40%).
All the above are part of the Halogen family of water treatment materials.
Cyanuric Acid is generally used in pools that are drained down, cleaned out at the start of the year, and refilled with new water.
Pool owners using salt water generators’ should use Cyanuric Acid to stabilise against chlorine loss.
Cyanuric Acid is added to pool water at approximately 1kg per 35m³ (2lbs per 7500 galls).
The object of this practise is to hold chlorine in pool water to safe guard against both dissipation from both heat and UV loss.
Cyanuric Acid levels should not go above 20 to 40 mgm/lt or 20-40ppm.
High levels of Cyanuric Acid will cause a problem known as ‘Chlorine lock’ and result with pool owners having to pump valuable heated water down the drain affecting the ecology , environment and bank balances.
