Why does my ph keep rising...

[Gibson00]

Lately having an issue with ph wanting to keep climbing to 8.

New fill of water less than 2 weeks ago.  Clean filters.

Balanced TA to 70, then ph to 7.6-ish.

Chlorine tub, using dichlor (CYA not very high after only 2 weeks or so), with daily levels kept around 2-3ppm with a shock to 10-12ppm every 12 days or so.

Every day my ph is back up around 8 (taylor test kit).  What am I missing??

80's not to bad, try driving your PH down a bit more.

I meant TA, drop your TA a bit more.

Drop your TA, I keep mine at about 40.. keeps the PH in check pretty well. And as long as you use the air injectors in your jets, the PH will want to rise.. its normal.
