Just found out that Ace Hardware carries HTH 6-way drop test kit. I've been everywhere today looking for ANY test kit and ended up at the pool shop buying the very basic kit to get by. I fail to understand why the stores in South Carolina, where the pool season begins in April and ends in October, do not stock pool supplies once you hit July. It is slim picking! Off to Ace Hardware tomorow. Continued thanks to all for the advice!
