A few questions about adding salt to your pool

[RyanBC01]

A few questions about adding salt to your pool when you're using the BBB method....

1) Is it right that 25# of salt will raise salt 1,500 ppm for every 2,000 g?
2) So for my 29,000 g pool, I would need to add 362# to get my salt levels up at approx 1,500 ppm, correct?
3) How long does the salt levels last when you're not using it as a sanitizer? (I can expect my chlorine levels decrease about .5-1.0 / day at around 30 ppm CYA with a clear day)

Thanks for the help.

Re: Can I add salt to a chlorine pool?

I found on Morton's pool salt site, a table indicating about how much you should add...

It says 10 bags (40# per bag) should raise ppm to 3,000 for a 15,000 g pool.

So 1 bag should raise salt 300 ppm for a 15,000g pool if my math is right?

Never assume that your starting salt level is zero.

The Pool Calculator is really good at figuring out quantities.

Salt only goes down due to water loss, things like splash out, backwashing, and overflow. Thus you usually only need to add more once a year to replace what was lost the previous year.
