The HTH 6 way only did two CYA test. I tested the CYA when I got the test kit before I started to add bleach. I did test again before I added the first 8 gals account you but that in red in your instructions. The first was 120 and the second 4 days ago was 110.(new test kit shipped today) The pool is getting very clear. I just jumped in and the chlorine was a little hard on the eyes but not bad. Thanks for all the help again!! How would you sudjest I maintain the pool going forward?
