Yesterday I arrived at me ex her place who has a pool of approximately 30.000 liter. I noticed that the water was cloudy and she told me that her boyfriend just had poured 4kg of Soda ash lite in the pool.
I thought that's gonna be funny, as 4kg in that size of pool would raise the pH probably through the roof.
Today I went back with my digital pH tester and aquachek teststrips and expected to see some big problems.
I was surprised that the water was very clear, and tested only pH6.5.
Alkalinity was about 70, chlorine 0 and CYA over 150ppm. I knew about the CYA problem before and had warned her already.
It took me another 3kg of soda ash to get the pH to 7.3, which is definitely not normal.
Tested again and now TA was somewhere between 120 and 180ppm, but I expect more to the high end, and CYA of course over 150.
What can be the cause that the Soda ash doesn't register the way it should.
Could it be the high level of CYA or is Soda ash lite actually baking soda or something?
