But that's just me.
To the experts here isn't a kh of 40 and gh of 30 kinda reversed?
Just a thought.
worth at most .02
Ditto the plants, even some stems just left to float, that's about as easy and cheap as you can get.
If you read the test kit instructions, BBob, that's how the strips are incremented, different incrementation for each type of hardness... and it's ppm, not degrees. That's down in the under 6 or 7 d#H ranges or lower I think, so they are actually very similar numbers being only 10ppm apart. The charts only go to 12d#H for either type. I am sure that strips don't even measure that high in degrees.
Oh, you would be correct in theory but it also depends on the accuracy of the strip and the read of the colours. Mine were right side by side and I think the KH was one or two degrees higher but I would have to look at my log to be sure. The varied incrementation could easily account for the apparent discrepancy.
dGH = 30,60,120,180
