I am just starting to tackle the pool in our new house. We got the pool cover replaced and had someone come out to shock the pool and it was looking good for a couple of weeks. I want to do the maintenance myself and figure that a test kit is a top priority. I am looking at the TF-100 and see that one online retailer (http://tftestkits.net/TFTestkits-TF-100-p4.html) offers some add-ons to the test kit. Are any of these necessary? We have a SWG (I believe... we have an ECOmatic ESC 36... that's considered an SWG, right?). As you can see, I am a beginner here.
I haven't tested the water in a few weeks now and I noticed that it is just a touch cloudy. Today I checked the ECOmatic and I see that one of the lights is red, so I believe it needs some adjusting. I am not sure how old it is, so it could need replacing, or maybe not. It might need salt? One of the add-ons to the test kit is a "salt test strip." Is this how one goes about testing the salt content of the water? If not, how do you test the salt content? Thanks in advance for your help.
