Tom's "New CO2 revelations", led to a discussion (on another board) about using air which is .03% CO2 to get CO2 to plants. Shalu has been doing this with an air pump fed into a HOB. Tom suggested and I want to try using compressed air fed into a ceramic diffuser or something else to create microbubbles that would then be dispersed by a powerhead, the same as he's doing with CO2.
I'm going to start putting this together tomorrow and would like to hear any feedback. I have a compressor and a tank so that parts easy. Pressure would be low enough that regulating pressure should be easy but I'll have to research that a little bit. Then it's a matter of creating the microbubbles to disperse. I doubt anyone has a ceramic diffusor locally but I'll check. Another idea is a Duetto with aerator.
Open to ideas and suggestions........
