So I wanted to confirm my ph test, which kept turning pink despite low chlorine levels. The pool store also got 8.2+ (higher than their chart) and did some "acid demand test" and the lady said it gave an "adjusted ph" level of 16.9!
Just wondering if that is even possible, and does that mean I will need to put in 61 L of muriatic acid to correct this?!?
Funny thing is the pool was almost clear april 16th, and the ph was 7.4 as per the pool store. Only thing used since was some cal hypo for a few days, and bleach since then. Here is what the store's tests read:
acid demand 19 drops
adjusted ph 16.9
Any suggestions greatly appreciated, Thanks!
