Our pool set for two years before we started it back up last summer, at which time it had a hard white build up.

This year, there is more. From what I have read, this is likely calcium build up. I am looking for the best way to remove this. Some of it is stained green.

We bought a salt water system this year. Opened up the pool, pool was all clean. Would attempt to vacuum and the return was returning green, murky water. Let it set for a few days, pool return semi clear.

I got fed up putting money into and told husband to drain and we'd clean and start over. It is currently pretty much empty, so no test kit readings to report.

Would love to be able to clean the bulid up off the walls (which is also stained green in spots) before we refill this weekend.

Any tips? I've read to not use chemicals, but the BBB method. I will read that again and try to understand it a little more. It seems like we are pouring too much money into this pool in the way of chemicals, chlorine, etc.

Any tips would be appreciated.
