thank you for sharing. You helped me through the years watermom! I had to smile when you said about not even having to measure, I got mine down pretty good that way too. One of the things I take pride in for a pushing 60 year old also. Some one asked me how I knew how much to put in, I said I just dump. But, it isn't just that, I test every few days, eyeball it, just in tune with my pool, I guess. NOW, if I can make my 18-19 yr. liner last a few more years I will be happy. We have a leak somewhere? Thanks again for sharing! Pool people really do make you think, hmm, maybe I am crazy, it is nice to hear a testimony that that is not TRUE, smile! Even though we know better!Smile!
