I'm went to my sister's house tonight and she just bought the house. There is an inground pool (30ftx17ft 3.5ft to 5.5 ft depth) that they are trying to open. I believe its a sand filter and there is aquarite SWG. I took my TF-100 and tested their water. They pour liquid chlorine and algeacide in the pool on thursday
Test results from today:
Temp: not sure
salt 940 (test strip) unit says 1300
Just now we put in 20 lbs of salt and 2 bottles of shock.
I'm not sure where to start as I'm not sure how similar inground and above ground pools are. Their neighbor told them that there is always a cloudiness to the pool which I told them that the water would be crystal clear when we are done.
