My results after draining of water - thoughts?


Aug 13, 2010
I drained a little more than 1/2 my pool, and refilled with tap water. I intend to go with liquid chlorine now, instead of Trichlor / Cal-hypo the pool guys were using.

Just tested results:
25000 gallon inground, vinyl-lined pool
82 degrees (water)
Direct sun from 8am to 4pm daily.

CYa: 50
TA: 90
pH: 7.2 (LOW)
FC: 6.5
CC: 0
TC: 6.5
CH: 240

All good except pH. I added roughly 32oz by vol of soda ash. (I say roughly because I didn't have an exact measuring tool).

Do you think I'll now end up with too HIGH of a pH?
Probably not but if you do it will be easy to fix. Aeration would just be a means to raise the pH without adding chemicals.
