Yet another new pool owner here. We bought this house with a pool just before winter. After spending hours and hours on this site, I said good-bye to the pool guy, purchased a TF-100 test kit and just found out that CYA level is around 160 (half tap water method). And then decided to drain the pool.
However once the water level started to go down, I am seeing all the cracks that weren't obvious with the water in. Now I am wondering how bad these cracks are ? How long do I have before I will need a full re-plaster ? Pictures follow.
