You all have been very helpful for me with my new pool and now I need help figuring my moms pool out. She opened it a few weeks ago and has done what she always has done with shocking the pool till clear. Pool is clear. It is not holding Chlorine at all even over night. She is using granular 47.6% cal hypo for chlorine. I ran test with my kit and came up with the following,
I know that she needs stabilizer but before putting that in I wanted to make sure that there was no other underlying issues that could be causing this. She has been putting plenty of chlorine at night more then recommended for pool size and it reads nothing every morning. I did the same thing last night and the same. What are your recommendations?
