Let's see those '10 gardens

OK, I got out my fish tank electronic ph meter and checked it on a 8 ph cal pack and it was 8.04. My unsoftened tap water came back 7.78. I have a reverse osmosis/deionizer for fish tank water. It measures 6.74, slightly acid. This is right for very pure water. I used the RO/DI water to soak a big handful of the unused garden soil for about 15 min. It measured 7.75. Slightly base. I just checked it again and it's 7.67.
Somewhere I have a soil test kit for NPK. I should get a new one though, that one is, like, 15 years old or more. Waddaya think, Scott?
