Ok so PH is down to 7.3
CYA is 1ppm - typo CYA is 50
based on this my unsdstanding is that I should shock to FC of 20, is this correct?
I have addd 12 litres of liquid chlorine and have the pump, and solar pump running
Just checked FC its at 26.5
Yes not sure why the FC jumped so much, possibly an error on my part.
Gave everything a good scrub and will continue to do so. Come the weekend I will be able spend a bit more time on it during daylight hours.
