Hi all- am at my wit's end and hoping someone can help me out here! I feel like I should be able to figure this out but am getting nowhere. We had a pool put in last December, and opened mid-April. I started testing the pool chemistry about 4 weeks ago, and have been able to keep the Chlorine in range without much issue. The pH has always been on the high side (7.8-8.2). But where I'm completely lost is the alkalinity. I have never- not one time in testing 4-5/x a week- ever been able to get the color to change to indicate there is ANY alkalinity in the water. We even purchased a new test kit, thinking maybe there was something wrong with the first one- but no difference. I have added so much baking soda I'm surprised I can see the bottom of the pool. It never does anything but increase the pH. From all I've read, I should get the alkalinity right before tweaking anything else- but the Taylor test never ever changes from green to red, despite the number of drops I've added at a time (most I've added is 15 just to see if anything would happen- nothing). I just tested our tap water, as a point of comparison- and the same thing- vial stays green. The drop is only red for a second but when I start swirling it disappears to green. At any rate, I have combed these forums and online and have not found anyone with a similar issue. We use the net to skim daily, run our Polaris 1-2x/day, and the water is always clear and clean in appearance. Can someone advise on what may be going on and what I need to do? The last thing I want is to ruin our pool after having spent so much- we've waited decades for this and I don't want to screw it up! Thanks in advance for your help.
