The above commandments of pool keeping are for pools that already have been in service; is that correct?
The problem is: my nephew did not shock his pool after filling it with water. He has been just adding chlorine tablets and nothing else and testing for it. Yesterday, there were many children using the pool and today it is cloudy. So while he and his family go on vacation. I told him I would get the pool in shape and ready to use, when they come back. I already have the necessary chemicals to do this.
So my question is: Do I follow the subject commandments as recommended or should I shock first and then do #1 #2 and #4 afterwards?
This is a vinyl above ground pool of 2400 gallons capacity.
