I've been lurking for about a month now.
After a horrible summer last year...algae, pool store recommended phosphate treatment, more algae, new cartridges for my filter, etc....i am now using bleach exclusively. I have some old shock, pucks, and some calcium hypo that i will still keep around if i am desperate for chlorine.
I purchased one of the recommended test kits and have been testing regularly since opening in mid-April. I took a water sample to the pool store today, more out of curiosity than anything else, to compare their results to my results.
There are two outliers: the CH from the pool store reads 205 while i get 325 from the drop test. And, the pool store shows TA (input) of 100 and TA (adjusted) of 47 while i get 80-90.
The pool store uses the ClearCare Expert computerized system.
Any experience with the differences?
Thanks. Trouble Free Pool is a great blog!!! As an engineer, it is very comforting to see the chemistry supporting the method.
