Yup, simple ratio. OK. I guess I just didn't see it.

Good news on the KH test. My refrence solution reads out 10 dKH with the 
Aquairum Pharmeceuticals kit and 7 dKH with Hagen kit. Same amount of 
shift, regardless of scale.  So in refrence to NaHC03, the AP kit is 
accurate while the Hagen kit is not, yet strangely remains offset by 3 dKH.

Unfortunately I've been using NaHC03 for KH adjustment and using the 
Hagen kit to measure to 5 dKH, and actually having 8 dKH all this time. 
This means more actual CO2 than previously read. Then again, my fish 
have never gasped for air. Not even that time I acidentally got over 
130ppm CO2 in the tank.

It makes me think to just adjust the CO2 until the plants begin to pearl 
while the fish remain active.
Which brings me to another point. My plants are beginning to pearl! I've 
not seen them pearl off gas in over a year!

Lights, nutrients and CO2. It really does work. Doh!
