dittos greg....Awesome post eric, a great one stop water quality shopping resource!, and thanks greg for yer insights.
hmmmm......ok. i did find out that siemens are the SI (metric) designation for reciprocal resistivity (conductance) known in "american units" as mhos (either millimhos or micromhos). kind of like new math, but they are one in the same (one unit of mhos = one unit of siemens). so my EC is likely on the low side of aquaculture optimal and can only qualitatetively hint at alkalinity and hardness conditions in "most" cases. o.k., i'll take that. i was still pleasantly surprised by a pH over 7 given my water shed....i'll be keeping an eye on that, and if i have to, do i have to?, i'll pay for a water sample
thanks again guys.
