The standard size of the villa swimming pool is 25m in length, 1 1m in width, 1.6m in depth and 440m3 in capacity, which is a relatively standard size.

Matters needing attention in the use of swimming pool:

First, adjust the hardness of water. The hardness of water should be moderate. If it is too high, aggregate will appear on the pool wall. If it is too low, it will erode the mortar of the pool wall.

Secondly, in order to keep the pool water transparent and clean, total soluble solids (TDS) can be used for the reaction.

Thirdly, the pH value of stable pond water reflects the concentration of H+ or OH- in pond water. The pH value of pool water specified in Hygienic Standard for Water Quality of Artificial Swimming Pools ranges from 6.5 to 8.5. In order to ensure the reasonable operation of the swimming pool, users of the swimming pool should pay close attention to whether this index is up to standard, and the pH of water can be measured by simple test paper.
