DK,

Just saw your second post about test strips. Yeah, they're really not good for doing what you want to do.

Wal-Mart frequently has available an HTH 5-way kit that'll do in a pinch (only $15) but Ben's kit is THE SINGLE BEST INVESTMENT you will make in your pool.

In fact, since your water looks so good, you probably are in good shape and just need some accurate testing to confirm it.
