Chlorine levels are best kept a minimum consistent with healthy water
If stabilizer (Cyan uric Acid) is used, take care not to exceed 55 ppm, as this will give a false Total Alkalinity (TA) reading. Total Alkalinity (TA) should be 160 ppm.
Don’t confuse Total Alkalinity (TA) with pH.
The strong focus on diligence with Total Alkalinity (TA) is based on our 27 years experience with epoxy coatings under Australian water and climatic conditions. Most “Test Kit” recommendations are based on conditions in the USA, where, it must be remembered, it is cooler, further from the equator, and it is quite normal to empty the pool in winter time. to prevent expanding ice from destroying the pool structure, thus, in the USA, management of chalking is not a significant issue. In Australia, the UV is harsher and it is not recommended to empty the pool in winter. Australian pool construction is based along these lines, by keeping a pool empty over a extended time can cause damage to the structure so it is important to manage pool water chemistry through winter.
Finally, if you are having your pool water chemistry managed professionally (e.g. by a pool service shop), it is important that under pool type, you specify “Paint” rather then fiberglass, marble sheen or pebble, as paint is the surface presenting to the water. Paint requires higher Total Alkalinity (TA) then other surface types and incorrect specification can lead to Total Alkalinity (TA) being maintained a lower levels then those recommended above, with the attendant problems. These include faster rates of surface powdering, more “pick-up” on hands and feet and lower life expectancy of the epoxy coating.
With appropriate care, you can look forward to many years enjoyment form the smooth, beautiful finish of your new Epoxy coating.
