Just started up my new 10000 gal Pebbletec pool 2 weeks ago. The pool company came by within those 2 weeks a few times and took care of the water for me so I never tested it until now. Heres my results thus far.
CH=275 CYA=80-90 FC=4.0 CC=0 PH= 7.4-7.5 ALK=140-150
Water is 70 degrees

Any thoughts on what I need to do or does something need adjusting?
The SWG is coming within the next few weeks, where should I get my levels at before they install it? Any special preparations need to be made?
