Hi Walter,
The directions on my test kit (Hagen) state that after testing for KH (carbonate hardness), multiply the results by 0.56 for dKH, or 0.02 for mEq/L for the ALK readings.
My water generally tests at 190 for KH, so I get:
3.8 for mEq/L
10.6 for dKH
This is where I get confused
- some people give tank specs in dKH and some in mEq/L???
BTW, Hagen states that the GH test is not recommended for saltwater...

*Edited to fix my water specs, that I had mixed up - thanks Beverly!
