Brandin Posted January 6, 2021 Report Share Posted January 6, 2021 No matter what chemicals I add to my hot tub I cannot seem to make my free chlorine levels go up. It stays at zero. Been trying different shocks and such for about 3 weeks now. Right now it says my total chlorine is good. Free chlorine is zero Ph is around 7.6 Alkalinity is at 140 Cya cyanaric acid is right around zero as a side note (if it makes a difference) I am using the frog @ease chlorine/mineral system. Any help would be greatly appreciated. Quote Link to comment Share on other sites More sharing options...

RDspaguy Posted January 7, 2021 Report Share Posted January 7, 2021 Every new tub should be purged with Ahhsome spa jet and plumbing cleaner. Total chlorine, ideally, should be the same as free chlorine. Smartchlor will read as combined chlorine. Not sure what that frog floater uses, but I would toss it. I am a fan of mineral purifiers, but use the cartridge that goes in the filter area not a combo floater. You should have a good test kit, strips are unreliable. Depending on what shock you used your chlorine may be unaffected, giving false readings from mps, so high it is bleaching out the test, or your cya may be too high. Please provide detailed descriptions of exactly what you are using by active ingredient if listed. Does your spa have ozone or uv? Quote Link to comment Share on other sites More sharing options...
