Cyanuric acid is crucial in maintaining the proper chlorine and sanitization of pool water. The level should be professionally tested at least once a month and adjustments made accordingly. If the level is too low, it will make it difficult to maintain chlorine in the pool. If the level is too high, there will not be adequate sanitation. The chlorine tablets used whether stabilized or non-stabilized are the main contributing factor of the stabilizer level in the pool water. The adequate level is between 20-60ppm. Once the level exceeds this range, water will have to be displaced and fresh water added to dilute the amount present in the water. The water will need to be rebalanced.

Calcium levels in your pool are always present. Once a month you want to get the level tested and adjusted as needed. If the level is too high, you will produce white scaly buildup. If it is too low, you will most likely shorten the life of the plaster. Sometimes adding a sequestering agent will help. Draining the pool some and rebalancing may be the best solution, taking into consideration the calcium levels from your fill water. Maintaining proper PH levels is always the best way to limit the effects of high calcium.
