I am wondering if I should have started with filterd or purified water like the kind you buy at the grocery store (the 5 gallonn container). But that would seem to get kind of expensive.
I checked the pH of my DWC water with a pH strip tested and the drops (I have a pool so I have this stuff around), Both of these test methods verified that my
pH meter is working correctly.
I did email GH tech support and will check tomorrow if they replied. Thanks for the info aaand help.
