So I have been doing the TFP method for a year now and just had the liner changed in my pool a week ago. With the liner change they were supposed to put in all the startup chemicals. When I tested it the next day there was no chlorine in the pool. So I got the chlorine level to normal and tested everything else and it was good. The next day no chlorine again. So I am assuming they did not put any stabilizer in it, since no matter how much chlorine I put in it, its gone very quickly. I am out of the reagent to test CYA and have some on the way, but what should I do in the meantime? I am just eating through chlorine.
