New to the forum. Same story. New pool finished in October. Had the builders guys taking care of it till January. They had me using trichlor tabs and dichlor to shock. We have a chlorinator but they never used it, told me to just put pucks in the skimmer. Of course I wanted to use it when I took over maintenance. I could never get it regulated - my chlorine was always sky high. I kept it down to 1/2 on the lever valve but the only time my levels went down was when it was almost empty. Have been trying for months to get the pool builders maintenance guy back, thought it might have a valve problem and everything is still in warranty. I would open the chlorinator and the tall tube in the middle would not be attached - figured more chlorine than needed might be getting into pool. I was having water tested at Leslie's. I told them my chlorine stayed high and when I tested my CYA they were over 100. They consistantly came up with 35 or 40. Phosphates always were high so they would just tell me to take care of that. Pool builder and his maintenance guys won't respond. Started reading your forum and to make a long story short my TF100 test kit should be here by Wed. I turned off the chlorinator today got the 10% bleach at a different pool store. Had them do another water test.
Found your CYA/Chlorine chart and added 181 oz bleach using the pool calculator. I will do the OCLT test and hoping I won't have to drain 50% of my pool. We are getting alot of rain and I have been adding water with the garden hose. I have never added anything else to my pool but Orenda for metal and scale and I added something to up the CH from 150 several weeks ago.
Thanks, hoping to get a handle on all this. My husband has been a little worried - he thinks I have acquired an internet addiction. I am more than a little OCD when it comes to things like this. It is maddening when no one will answer your questions or acknowledge a problem.
