    do i need to raise my calcium

    I went to the pool store today and had them test my water just to compare to my test.They said I needed to add calcium.I thought tat if you had a vinyl liner you didn't have too.But the guy there told me if I didn't the water would leach it and cause wrinkles in our liner.What should I do?Here are my numbers. Thanks

    Re: do i need to raise my calcium

    Recommended levels in Pool School say you are good with CH from 50-300 with a vinyl liner. You said you were comparing test results. Did your testing show low CH also? It won't hurt anything for you to raise it a little if it will give you some peace of mind.
