Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm.
Do i need calcium in vinyl pool.
The first thing you ll want to do is remove calcium from pool water.
Low calcium as is often the case will cause long term serious damage especially to plaster vinyl liners grout in between tiles metal rails and even concrete decking around the pool.
Yes calcium is still important to all types of pools.
If you have a concrete or plaster pool keep the level between 200 ppm and 275 ppm.
The optimal calcium level is 200 400 ppm.
It s ok to wait a week or so on the calcium while you fix the other issues.
A higher ppm causes deposits on the surface and cloudy water.
Generally i don t have my customers deal with the calcium until the pool is sanitized and clear.
If a vinyl liner s calcium level is too low this soft water situation could lead to foaming and other water problems and can harm the vinyl.
Low calcium levels in the pool calcium on the low and high end of the scales will eventually cause problems and when they do be ready for some serious problems.
However it s not as big or pressing of an issue as chlorine ph and all the other stuff.
When you retest the pool water the alkalinity should be lower.
Here s your favorite answer.
Then refill the pool adjusting the alkalinity.
But what it depends on isn t that difficult.
