Drop Checker Question

I'm trying to get my Planted Betta tank straightened out with the help of some forum members and have a question about liquid Carbon sources and the use of a Drop Checker.

I don't have a place to keep a CO2 tank because my 12g Fluval Edge is sitting on the kitchen counter, so I have been using FlorinAxis as a Carbon Source. It was recommended to my by the LFS as a CO2 tank replacement.

My assumption is that it won't work, as the liquid source is most likely an organic. If it won't work, how would I go about monitoring the CO2 level in a tank using a liquid Carbon source?

Don't bother.
Use the material per label directions.
Monitor the plants.

The drop checker will still work for CO2, but your tank will have other sources of carbon, too. When the DC shows low CO2 levels that is OK because you are giving the plants carbon from another source.

Most if not all liquid carbon is a glutaraldehyde containing product. Using liquid carbon dose the recommended amount per the instructions once a day. If you have a heavily planted tank you can double dose.

I read somewhere the half life is 12 to 24 hours, hence the need to dose every day. There is no real way to monitor the levels of a liquid CO2 product in your tank.

I agree with Yomon as my understanding is that the liquid carbon mixtures do not contain free molecules of CO2 and would not therefore register on a drop checker. Just follow the dosing instructions.
