Hello TFP friends,
I purchased a HTH 6-Way Test Kit, and here are 5 of the 6 results;
Total Chlorine = 5ppm
pH = 7.6
Alkalinity = 80ppm
CYA = 40ppm
My question is related to the total hardness results. The test calls for 5 drops of the hardness indicator and it should turn red if hardness is present. I'm puzzled by what I should be seeing and what the results might indicate.
When I add each drop it turns red momentarily and when I swirl it disappears. It takes 10 drops (instead of 5) for the water to fully turn red (more like a bright magenta), and 15 drops of the titrant to turn blue.
My pool has a 25 gauge vinyl liner. My water looks and feels great. If I drop my chlorine just slightly to get it in the ideal range could that be enough to impact the TH? And, also, do I need to be concerned about this anyway given I have a vinyl liner and not plaster? The sheet says low total hardness will cause foaming and damage plaster surfaces (neither of which I have).
Thank you as always!
