My pool is four years old and nobody ever measured total hardness until now.
Low calcium hardness in vinyl pools.
Low calcium levels in the pool.
My ch tested today was 90.
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.
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.
Hi i have a vinyl pool i read that calcium hardness is not that important for vinyl pools.
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.
Calcium for a liner pool can be a bit lower than a plaster pool in the range of 150 250 ppm.
Just a quick question y all.
Does a salt water generator count.
Is it really necessary to have the calcium hardness up to levels in a vinyl pool.
Calcium hardness is also very important to the chemical balancing of your vinyl liner swimming pool.
Is this really needed to keep the water correct or just important for concrete pools.
It is at 75 ppm.
Just tested the water per ben s pool testing kit and my calcium hardness is 60ppm which is low.
Calcium on the low and high end of the scales will eventually cause problems and when they do be ready for some serious problems.
Thanks for the heads up here.
I have read that the ch should be between 200 and 400 but that it does not matter for vinyl pools.
Oh wow i was just about to buy calcium carb for my vinyl pool.
