CC test question

[CarlD]

If you use 25ml, each drop indicates .2 ppm (5 drops = 1ppm).

Thanks Carl- I thought it was possibly you who posted last year how to test CC below .5 by filling to 25ml, so was hoping you'd reply. I laid in bed last night thinking about this, sleep is over-rated anyway, lol, and concluded too that it must be .2 per drop since I tested at .4 all last summer. Thanks for confirming this for me. My pool's running .4 again this year. All of my chemical levels are consistent from last year, and the amounts of bleach I use and muratic acid are also consistent. Thankfully most of you don't have to deal with iron like us in NE, but it's under control, and like your signature says: it truly only does take a couple minutes a day to keep crystal clear water! Thanks again for all you moderators do, and the countless hours you put in for all of us!
