Hi guys.
After a bit of quick research I can see that electronic CO2 meters are very expensive...
I have a chemical pH test kit, but find it difficult to read and all too easy to interpret the colour as different values coupled with the poor resolution at the lower pH levels...usual criticisms...
So I was thinking of buying an electronic pH meter, as they aren't too badly priced (I can pick one up for under $100 AU).
Are there any specific types, brands of these meters that are better, or are they all essentially the same?
Could a pH meter be dragged about the aquarium to get some idea of relative CO2 levels? I would expect the pH to be lower in the open water, higher in the plant beds where the CO2 levels are lower. kH would be constant throughout the tank correct?
