Hi! I'm brand new to membership, but have spent a lot of time reading pool school and pool math. I love all the info, thanks everyone! I am not having any problems with my pool; I simply want to convert from perma salt to BBB. Although I cannot find a post with specific step by step instructions, I am hoping there is one that someone can point me to? From what I've read, is it correct that I can leave the salt in the pool? Can I just lower the copper with sequestrants, or do I really need to drain and refill? Thanks in advance for your suggestions!
