Okay so our salt cell went out about 2 weeks ago-ish.
I've noticed what looks like some slight algae building up on the walls of the pool and spa. (picture attached).
I've just received our new salt cell and was about to install it but thought to ask TFP first what you all think I should do?
Do I install and shock, or shock then install or what are your thoughts?
Test as of today:
TA=170 (always high as we have very hard water)
CH=280 (see above about hard water)
As stated this will become or was a salt pool before and I just got the brand new salt cell ready to install.
ANy and all help will greatly be appreciated.
