calcium hardness levels

[davidwest]

hello, can anyone let me know if calcium level of 400 is acceptable. pool remodel is almost one year old, first mistake i made was having the pool store test my water, the had me add calcium powder, I'm not sure if that was the right thing to do. I no longer go to the pool store and do all my own testing.
Thanks

400 is creeping towards too high. It is manageable at 400, just don't let the pH rise over 7.5 and try not to add any more calcium products to the pool.
