I started with TFP mid season last year So this is my first opening. What sequence do I open the pool. Do I test water immediately and then balance chlorine and pH accordingly. Or do I add chlorine right away and then go from there.I have a SWG so my plan is to use liquid chlorine until my cell can generate. I am under the assumption when the water warms up a little bit the salt cell will start generating. Thanks in advance for any advice.
