Your PH is way high. In your first post, you said your PH was high, so you added Borax. Wrong direction! Borax RAISES ph - the proof appears to be that your PH is now 8.4. It needs to be in the 7.2 to 7.6 range. You need to add acid, either muriatic or PH down.

I think once your PH is in range, then you can start to work on the other issues.
