Hello Everyone, so excited to be back on the forum. I have been a member since 2014. I woke up one day to a green pool and found this forum, So many of you helped me until we figured it out!!! I never went back to the pool store again!! Well, we sold our house 4 years ago along with the pool. Building starts today on my new pool!!!! Its been awhile and I want to start out on the right track. My main issue before was my CYA way too high. So here is my question, I know they are going to give me a supply of shock which I would like to use just so not to waste. I don't want to add stabilizer until the shock is gone and I switch to liquid chlorine. Is there any harm in not adding stabilizer to my new pool for a bit? Any other advise on adding chemicals to a new fill would be greatly appreciated!!
