Thanks everyone. Luckily, my Ph has been below 7.2 since startup (fighting high Ph issues with SWG and new pool), so it must just be the new pool issue.

I understand the general consensus is the only way to get rid of calcium from the water is to drain and refill (i.e. dilute it). Anyone heard of anything else.

Moderators - if this should be a new thread because it is a 'new' question, let me know and I'll re-post.

Thanks
