PaulR Posted August 1, 2009 Report Share Posted August 1, 2009 If you have some distilled water you can dilute the pool water 50-50 with the distilled, test that mixture, then double the reading. Or you can get a FAS-DPD test separately from Taylor, or from tftestkits.net. The FAS-DPD will reliably measure up to 50ppm FC. --paulr Quote Link to comment Share on other sites More sharing options...

PaulR Posted August 1, 2009 Report Share Posted August 1, 2009 I am responding to this: I purchased a Taylor Test Kit K2005 (they didn't have a K2006) followed by this: This evening's readings of the pool water are: Free Chlorine=5 (the darkest reading) Total Chlorine=5 (the darkest reading) PH: 8.0 Acid Demand = 3 drops to 7.4 Alkalinity: 12 drops or 120ppm Calcium hardness: 45 drops x 10 for 450 CYA: 58 ppm The color-matching chlorine tests such as the DPD in the K-2005 behave a little erratically over FC5, in my experience, and I was trying to inject a note of caution because the phenol-red pH test definitely reads too high when FC gets higher than about 10. But in re-reading the posts I see that pH has been 8.0 pretty much all along, even at low FC, so "never mind." --paulr Quote Link to comment Share on other sites More sharing options...
Landene Posted November 23, 2009 Report Share Posted November 23, 2009 I think Muriatic will be better for this than dry acid, although handling the muriatic requires more caution.The chemical is dangerous..Keep a safety procedures by using it..
