Hi i have a vinyl pool i read that calcium hardness is not that important for vinyl pools.
Low calcium hardness in vinyl pools.
I have read that the ch should be between 200 and 400 but that it does not matter for vinyl pools.
Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm.
I read above that i only have to add calcium carb to a vinyl lined pool if there is equipment that can be hurt by low hardness.
Just tested the water per ben s pool testing kit and my calcium hardness is 60ppm which is low.
My ch tested today was 90.
Just a quick question y all.
Is it really necessary to have the calcium hardness up to levels in a vinyl pool.
Is this really needed to keep the water correct or just important for concrete pools.
Oh wow i was just about to buy calcium carb for my vinyl pool.
Soft water low calcium levels can cause plaster or concrete pool walls to lose their calcium to the pool water and can cause vinyl pools to lose their elasticity.
It is at 75 ppm.
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.
Calcium on the low and high end of the scales will eventually cause problems and when they do be ready for some serious problems.
My pool is four years old and nobody ever measured total hardness until now.
Does a salt water generator count.
This can be a very expensive problem so pool owners need to address low calcium quickly.
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.
