RE: Low pH?

[Michael Meyer <mikeymeyer@sprintmail.com>]

I have been told Culligan sells them inexpensively.  I was told they were 
not accurate to the hundredths, but if the are accurate to the tenths of a 
pH that would work for me.  I was going to call for myself since my pH 
meter is now reading negative numbers for pH.  Talk about low pH.  ;)

Electronic pH meters. You can find them online or check with your local
pharmacist, who buys them for store use all the time.

You don't buffer a pH that low.  You "live on the edge".  Keep your eyes on 
it.  Check it twice a day, and keep up your standard tank maintenance.
