I am running a salt chlorinator and this year put a safety cover on my pool in early October. I made sure the salt level was around 3100 ppm before putting on the cover (suggested range). I turned the generator down from 40 to 20 % and left the low speed pump running without testing the water chemistry but checking the salt level (which is automatic and doesn't require removal of the cover.) After a lot of rain, I pulled back the cover to put more salt in and tested the water. I have been unable to get an accurate reading with any test kit. I have ordered the Taylor 2006. What I did notice is that the OTO fluid in the yellow bottle did not mix with the pool water but looked turned dark orange and appeared like little drops kind of like oil trying to mix with water. I then tested straight bleach in my tester, and the OTO did something similar. I tested distilled water in the tester, and the OTO did not change color as expected. So, I've concluded that I have basically bleach for pool water.
I have tried Leslie's Chlorine Reducer but all it did was allow the OTO to mix with the water but is still dark orange. Perhaps I need much more, but I don't know how much as I don't know how high the chlorine level is. I've also left the cover off for several days and the sun has been shining. I've tried the dilution method of testing (1 part pool water to 2 parts distilled water) and have been unable to get a good reading even when I change the ratio to 1:10. I tried using all distilled water and only a drop of pool water with only 1 drop of the OTO fuild instead of 5 and the color was in a normal range then. Any ideas how I should proceed?
I don't plan to close the pool for the winter, but I will keep the pump running to avoid freezing. I have a high water table so I can't drain the pool in the winter either.
Thanks for any help!
