First of all, thx a lot for this site, what I know about pool I have learned here !
When starting to turn my pool into shape and form and based on the guidelines here at TFP, among other problems I have had to raise the CH.
Temp 91 F
Water appears crystal clear.
To get to this level of CH I have added 14 kg. (31 lbs) CH+ (Calcium chloride) during a 2 weeks period. It seems like after a couple of days suddenly the calcium ends up on the bottom like white/greyish powder that is rather hard getting loose, I need to help my robot manually scrubbing. My sandfilter is able to catch and hold most of it. I have also noticed that the steel latter has been covered and not shiny blank as before.
I am using bleach for sanitation and Calcium hypo for schock.
Any ideas on this will be highly appreciated.
