Clear Pool with High Nitrates & high Chlorine consumption

[Flying Tivo]

Needs to be covered during the day

@cowboycasey it seams a cover is the cheaper alternative for now, until you can drain.

While we cannot rule out Bromine, would there be any harm now in raising the CYA to 40’ish even to to see if chlorine use is reduced?

My water temp is 82 right now. Not sure the temperature of my well water but it stays cold. Likely in the low 60's high 50's.

I called United Chemical and talked to their tech about Pink Treat. He said it would take hundreds of bottles to cause a Bromine change to the pool. He claims he fights this stigma all the time. I'm not shocked at his answer. Just thought I would share. I'm good with raising the CVA. Don't see how that could harm much at this point. Cover might save me money in the long run as well. Is that your experience?

4 lbs of sodium bromide is about 14 ppm. So, about that much of your reading will be bromine vs. chlorine. If your chlorine was 28 ppm, half would be bromine and half would be chlorine. The bromine part would get reduced to bromide by the UV and the remaining chlorine would quickly reoxidize the bromide back to bromine. So, all it takes is a small amount of bromide to cause big problems.

Note: Rough calculations, not exact.

Draining risks floating the pool if the ground water is high and plaster exposed to the sun can become unbounded from the gunite.

You could do the tarp method if you want.

As some of you may know, my pool has been quite problematic with metal staining for many years. For the past 3 years I had been using Metal Magic to control the metal staining but lately, I've been having to use about 2 quarts of Metal Magic a week and have been having problems with chlorine...

You can try a higher CYA and/or use a cover. Switching to SWG might allow you to maintain the pool without a drain and refill.

Thanks for all the ideas. Any ideas on a cover that wont break the bank?

Thought I would report back that after a long process I raised my CYA to about 60 and my pool is now holding chlorine. What an adventure!
