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??
