Jp5608 Posted July 19, 2020 Report Share Posted July 19, 2020 I have a 16000 gallon chlorine plaster in ground pool and I accidentally added 15 ounces of a product called no more problems which is a sodium bromine (43%) product over the course of 4 weeks to my pool. 5 ounces each week or so. Prior to doing this I had a constant low chlorine reading of 0.5 which I was continuously shocking with cal hypo. I couldn't get it to go up. My ph is 7.4 Hardness 300 Alkalinity 130 Cya 65 The stuff I added was a liquid clarifier type product. I've been told only way to remove it now is drain pool. I'm still getting a 0.5 reading of chlorine. Is this small amount of Bromine something to worry about or has it burned off? Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted July 20, 2020 Report Share Posted July 20, 2020 Nothing to worry about. Unless you have a salt system your cya is too high. What are you testing with? Quote Link to comment Share on other sites More sharing options...
Jp5608 Posted July 20, 2020 Author Report Share Posted July 20, 2020 Taylor k2006 kit. My local pool store states my cya should be at 80 minimum for plaster pool. I'm at 65. ? What should I be? Quote Link to comment Share on other sites More sharing options...

rspar Posted August 20, 2020 Report Share Posted August 20, 2020 65 is fine, surprised your pH is 7.4 with that alkalinity. Sodium Bromide converts chlorine to bromine which is not effected by cya have you tried keeping a floater in the pool? A lot of guys used to run pools this way, add sodium bromide every week and keep tabs in the pool. Apparently it works for some. In my experience sodium bromide breaks down slowly over the season it's my primary algaecide. Quote Link to comment Share on other sites More sharing options...
