HELP!!!! Is this possible?

OK, I have a 4g nano set up with DIY CO2. I have the bubbles going directly into the filter intake. I know the pH & KH CO2 chart isn't perfect, but according to the chart, with my pH @ 6.5 and KH @ 10 the chart says my CO2 is 94. That can't be possible with DIY, can it?

Are there any fish in the tank? If there is, then you'll know if the CO2 is high if they're gasping at the surface (if the CO2 is that high, they'd be dead).

Here's another way to measure your CO2 (scroll down to the very bottom): http://www.rexgrigg.com/Algae1.html

The pH/KH relationship chart doesnt work in an aquarium, due to the myriad amount of buffers present.

But thats why we use drop checkers, cause in that isolated bubble, we can to a degree trust that relationship.

No, there are not any fish in there now. I had some in there until I rescaped the other day. I put them into another aquarium. I plan on getting some more next week.

Thats what I thought. I use drop checkers on my other aquariums. I have one coming for this one too, but its not here yet so that is why I tried the chart.
