Now to add insult to injury there is a 2foot vertical crack that I noticed in the deep end wall today while brushing the pool.

We had all our chemical levels perfect upon close, the pool company did all my opennings and closings. Not sure what they added.

The pool is only 2 years old and we have always had issues with the acidity. We have gone through huge amounts of dry acid and muriatic acid trying to keep pH levels down. We have brushed the pool weekly (2x a day in the beginning).
