Hi, on the subject of testers, I purchased a dissolved solids tester by Hanna 
Instruments for $20.00 that is supposed to 
test heavy solids in water.  The water filter that I am using, from Pure 
Royalty (Global Technology Solutions, Inc)
tests 000 with this tester.  I drink this water, but I still use distilled 
water to make my cs.  My distilled water from 
Safeway (Alhambra) tests 058.  I do not know what that means.  What are other 
testers on the market that will give me some
indication of what is going on with my cs?  And where can I find them?  Or...is 
testing of any kind with these kind 
of inexpensive tools just a waste?
Thanks,
Lon
