That is the biggest pool I've heard of! I'd love to see some pictures of it sometime.

Find out what your CYA is, then you can use the "best guess chart" to see what level to keep your chlorine.. then you can use the bleach calc. to see how much bleach you will need to keep the pool within your target range.

The BBB system really is fantastic, and with a pool that size I'd imagine it will save you some $$ too.
