I’m new to this forum. I’ve had a 17x33 above ground pool. It used to be a salt water pool but we’ve converted to a chlorine pool when the salt water chlorinator went out. I took care of it for 2 years myself then moved to using other people to take care of it. This is a vacation home for us so I’m not down there all of the time. After going through six different pool people that I’m paying to still have a green pool I’m gonna start taking care of it myself. I just purchased a Taylor 2006c test kit and will be going down next week to start working on it. Any thoughts on first thing I need to do
