    Re: pool chemistry

    First, lower your PH down to around 7.4, confirm that PH really is around 7.4 (doesn't need to be perfect, but not way off either). Then measure your TA again, and raise TA to about 70.

    With a SWG, you want to raise your CYA level to around 80.

    Your salt level look like it is probably a bit low. Check your SWG manual and raise salt to 100 or 200 above the recommended ideal level.
