Thank you so much for welcoming me to the forum.
Here is a little history: I have a 35-40,000 gallon inground diving pool with pebble tec finish. This pool originally was built in the '80s we upgraded the filter (to sand) and pump two months ago. Complete water change with chlorine wash one month ago. We did have a professional pool company coming in for weekly pool service (chems included). It turned into so much of a hassle and cause for anxiety since we were doing most of the work. I can empty leaf catcher, pool skimmer, pump basket, maintain pool cleaner (4 wheel bottom cleaner), and back wash!!!! Chems kind of scare me..

Sooo... Two questions:
1) How do I keep my Chems balanced on a new water change? Chlorine still has a hard time registering after 1 month
2) How do I continue to have a successful pool?

Thanks so much!!
