Just as long as you know that this is not "straight" laterite.
According to the information Karl released on the Newsgroup, it
also contains phosphate and nitrate.

The pH of our water doesn't change much during the year. It comes
out of the tap below 6 (full of CO2) and bounces to 8+ within 24
hours. (you think _you've_ got problems ;-) It's the copper
content that changes.
From what I've heard about your water supply, except for the
possible copper content, our water supplies have little in common.
Our water comes from three town owned wells. They switch to, or
more correctly, add in the third well during dry periods. (Not
this spring by golly... we're heavy into mosquito breeding around
here at the moment!) The pH doesn't change, but the copper level
rises from .25 - .5 ppm to over 3 ppm. Even without testing the
water, which I do if I'm suspicious, you can tell when they've
switched wells because all the plumbing fixtures in the house turn
bright blue/green. When it's worst, if you leave a bucket of
water or the horses' water troughs sitting for 24 hour (until the
pH rises) you will find a blue/green powder coating the bottom of

Can't say I miss the snails, but I'd sure love to be able to
maintain some FW shrimp!
