Question for all you acidwater collectors:
What's a good colorimetric test kit or inexpensive
meter for measuring pH in the 4.0 to 6.0 range in very
soft, low conductivity aquarium water ? (Some meters
dont work well-in-low conductivity, or lose their
probe ions quickly). Please be specific if you have a
meter or test kit to recommend. I dont need high
accuracy; +/- 0.2 is good enough.

To those also on the Anubias Design group list, Sorry
if i already bored you with this issue, but i'd like
more opinions.
