Hello,
I am using the Taylor 9-Way K-1005 Test Kit. It's the same kit I used last year, and bought a new one to start this year off.
I'm in the process of opening the pool. Shocked the pool and was in the process of getting the pool chlorine injector dialed in to maintain last years chlorine level, which is 5-6 ppm Free Chlorine.
Anyway, all my readings looks good and are back to last years levels, except my total chlorine readings have me at a loss.
So, the first measurement I took with the new K-1005 kit read 5 ppm Free Chlorine, but added the R0003, and that reads 3 ppm taken immediately (as instructed). That's not possible.
So I thought I did something wrong (miscounted drops), so I tested again. Again I got 5 ppm Free, 3 ppm Total. At this point, I assumed I got some bad reagent or something. So I broke out the remaining kit from last year. Chemicals left in it have a use by 9/22 date on them, so should still be good.
Took the reading again with the old kit and again, got 5 ppm Free, 3 ppm Total. An impossible reading.
So I turned off the chlorine injector for 3-days, let the pump run its normal schedule (10 hours a day). Had one day of rain that raised pool level about an inch (probably close to 500 gallons of water). I measure again with the new kit. I got a Free Chlorine of 3 ppm and total chlorine of 1 ppm. Again, an impossible reading. I didn't bother trying the old kit again.
I don't really know what is going on. All last year, using the same kit, I had no color change when adding R-0003 to measure total chlorine, which indicated no combined chlorine. It's not possible for combined chlorine to be negative, so I don't understand how two kits (last years and a new one), are showing this. It is clearly a lighter shade of pink both times after adding R-0003.
Is there some other chemical that could be in the water that effects this reagent that the test kit would otherwise not pickup? Or temperature (water temp only 68F still)? Other levels are fine, and water looks good, Everything but TC back to last years swim levels. I just don't like that I am getting a reading that shouldn't be possible. Makes me think something else is wrong I'm not catching. Maybe some chemical leeched into the pool or off the new winter pool cover, effecting this reading. I don't know.
