I've had my chlorine pool uncovered for about 2 weeks now. The water is clear but I've been waiting for my test kit. Got my test kit today and took my first set of readings. All i have done over the winter is to add power powder plus once every 3 weeks and I have kept a chlorine tablet floater in the pool all winter. I still have some chlorine tablets and some of that powder that I want to use up before I start buying the liquid chlorine. According to the laminated instructions that come with the test kit, from what I can tell my readings are good. Take a look and tell me what y'all think and please let me know if there's something that needs corrected.
