I did a 50% water change. My PH is showing around 7.2 with the PH test but the High PH test is showing a deep purple which would be an 8.8!
Confused!
Don't forget to let your water gas off before taking your Ph test. Right out of the tap will also be different than 24 hours later.
You are lucky then. Not everyone has that same result. It will differ based on your water source.I've heard that too. Right out of the tap, my water is 8.2 - 8.4. If I let it sit for 24 hours with no treatment, it is still 8.2 - 8.4.
