Yeap, same here. I wiped the eggs off the glass thinking they were snails pretty dumb huh? There's a guy in Tappahannock who's been into tanks and lived locally for over 3 decades at least. i live on the water have well water also. The well is an artisian it has to be or I'd be drinking Yecomico/Potomac water. I've never tested the Kh or the Gh.
