Use for test strips!

I know these things are frowned upon... but I ran out of 0870 and 0871 while Slamming (fortunately right at the end), have to wait a day or 2 for new to arrive. Previous owner used pool service and strips, so I had some. Put a strip in and FC reads deep purple (= +10). As long as I test purple I can hold off adding Clorox. Just hope the chemicals get here soon! I assume they are accurate enough to be within 2 or 3 ppm. I HATE going to the pool store for anything.

Perhaps it's better than nothing at all for a couple of days.

I know measuring pH is useless with high FC, but I "typically" have to add 16 oz every other day. It's been 3 days from when I started slamming (I'm done). Should I add a quart of acid just as an estimate to what I know it'll need, or just wait until FC goes to 5 or 6? Shouldn't mess anything should it?

I would wait until FC drops below 10 ppm before testing pH. Maybe your reagents will arrive by then.
