lower chlorine levels in heated indoor saltwater pool
by: Anonymous

I encountered a problem with lowering the chlorine and pH levels in my 10,000 gallon heated indoor saltwater pool. The last treatment of chlorine neutralizer brought the levels to zero then the most recent treatment of chlorine neutralizer (8 oz b/c of fear of levels dropping too much) has not had an effect. Same results have occurred with adding 32 oz of muriatic acid, the readings did not change.




Hello. I can assume thiosulfate was used. it sounds like possibly too much was added which means you're basically starting in the negative with chlorine.

Thio can also skew the pH reading as well. It's best to start adding chlorine, allow to filter for 7 - 8 hours then retest and make another chlorine adjustment if needed. The pH in the chlorine will also increase the pool's pH.

pH Is A Must
by: Anonymous

Not entirely sure what is meant by you aren't to check Alkalinity and pH if Chlorine is high. I run a salt water pool using a Cat Controller and Aqua Rite combination system. This allows me to maintain an ORP of 700 in my pool and 800 in my Spa.

Now I super Chlorinate after high usage and naturally if Pseudomanas or Coliform come back positive on a health board test. With Pseudomonas I super Chlorinate to levels of 50+ ppm and have no difficulty maintaining a ph of 7.2, Alkalinity of 100 and Hardness of 200.

The simple fact is, that if your pH is not maintained at levels between 7.0 and 7.6 then your Chlorine becomes ineffective. In other words pH is a must if you expect to kill bacteria.

So if you have done regular monitoring and find your levels are as I mentioned then you shouldn't notice any major changes when super chlorinating, at least I don't.

Good luck.
