Not sure if I have this right... Just started taking care of the pool myself. Joined TFP (awesome site!) got the test kit and things have been going well. I kind of enjoy knowing whats going on with the chemicals.
Today when I went to look at the pool I noticed what looks like salt build up on a bunch of areas along the walls of the pool.
Hoping someone can look at the pic and let me know whats going on or if this is normal. I can't ever remember seeing this but who knows.
