Hi to all.
i have just started taking care of a 40,000 liter pool, with a SWG and pH controller.
after reading through the very helpfull pool school for a while, i still couldnt find an answer for these following questions.
first of all- the chlorine solid tablets, do they contain CYA?
Is it dangerous for the pH controller to be on when pepole are swimming in the pool?
I keep on adding salt, and the SWG keeps telling me to add some more, there are about 70 people swimming in the pool per day, and it is outdoors, i assume those details are connected, but how much approx KG salt would the SWG need? it is set to 100% which i couldn't realize exactly of what.
the pool has a sand filter, how often should it be backwashed?
Id really appreciate your help.
