(1)Adjust PH value: PH regulator generally use tablet alkali and hydrochloric acid. When the pool water uses tap water, the PH value of the pool water is generally 6.5—8.5, and there is no need to adjust the PH value. When PH is low, use sodium carbonate or sodium hydroxide to improve the alkalinity of the pool water. When the PH of the water is high, reaching more than 8.2, the appropriate amount of hydrochloric acid can be put in. When adjusting the PH value should be dissolved first, and then use the dosing pump to add, or directly into the pool of circulating water inlet, start the circulating pump to promote the water flow to make it evenly distributed.

(2)chlorine-containing disinfection drugs, when the water temperature reaches more than 30 degrees Celsius, or the water color turns green, to appropriately increase the dosage.

(3) Use of anti-bath drugs：

Algae can be removed by regularly increasing the concentration of chlorinated disinfectant. If insects or moss are found, the bath agent copper sulfate can be put into the water of the input pool. The dosage of copper sulfate should be 2~3gM water.
