I got the Taylor K-2006 test kit this season (first time pool owner) and from day 1 the R-0870 powder has had a good bit of large-ish crystals in it. Is this typical? I feel like the large/chunky crystals make it difficult to accurately measure the amount when testing. Also, the powder seems to stick to the dropper which makes it doubly hard to measure as I know I'm not getting an accurate amount.

I could get something to grind the crystals if needed. Doesn't seem like I should need to do that but not a big deal. And do others of you have to regularly clean the dropper?
