Ok a little back story. We just bought out house so this is the first year we have opened the pool. It is an in ground vinyl pool. 19700 gallons. We switched it from baquacil to chlorine when we opened. We were using a pool store and their advice and chemicals. Well they are no help. We can't seem to keep chlorine in the pool. It will hold over night and barely drop but as soon as the sun comes up and hits the pool, it is gone. We tried using the skimmer sticks they provided and it didnt work. then we found TFP so we have been using liquid chlorine. It has worked the best out of anything but we are spending a ton on chlorine just so we can swim a couple hours before its gone again. I have the recommended test on the way but it wont be here until Monday. I'm hoping that some of the smart cookies in here will have some advice on what might be going on. Here's the numbers the pool store gave me today.
