Hi
I live in Denmark with strict requirements on semipublic pools. We've therefore been required to have an automated system for measurement and dosing of chlorine and pH.
We had a professional pool company configure a system which was based around a Intellichlor IC40 SWG.
The measurement of chlorine was through an amperometric chlorine sensor. We first had one system and then another from Prominent was installed (Dulcometer).
We had a problem that both system after a few hours started measuring way too low levels of chlorine compared to the actual value.
Even though I had asked them a few times (I'm a complete amateur having studied only a little on the internet on our issues) if it could be related to the current CYA levels in the pool, they didn't really answer that and put focus on it. Levels were around 30 ppm CYA.
Suddenly they gave up on reinstalling different systems and sensors and they got to the clear conclusion that WITHOUT DOUBT this was due to cyanuric acid in the pool giving too low readings, something which was even mentioned in a small note in the first system's manual.
We have now drained the pool water completely and refilled with fresh water to remove CYA.
But now, my question, I am worried if the non-existent cyanuric acid will make the chlorine disappear constantly, thereby causing the SWG to run 80% of the day?
We will run at a Free Chlorine level around 1.5 mg/L as specified by our government.
I know it doesn't cost anything to produce chlorine with the SWG, but if the cell is worn down every year, then that's pretty costly.
What are you comments on this?
Thanks and best regards,
Martin from Denmark
