Eric, thank you for the link and the pictures. Bill C concurs with your statement about being cautious of photos, especially the one shown.

Bill, I did a search for PaPond and found the link where he mentions aquarium test kits.

I found an additional post where PaPond mentions that he uses CHEMetrics test kits. I'll have to do some more searching later this evening.

Bill/Eric, I'd like to hear your thoughts on whether or not you think the snails that inhabit my pond could lead to problems for the BG.
