Reactor Problem

Flohrie-my understanding of the gravel vac reactor is that the longer the CO2 bubbles stay in the tube the more of it gets disolved into the water, the fewer bubbles you are blowing around your tank. That is why some designs show the CO2 line going into the vac tube instead of the powerhead. The water pushing through the sponge causes the CO2 to break up even more.

At least that's what I thought. I am sure someone will correct me if I am wrong;) .
 
As usual, Skittyfish is correct-o-mundo. The bubbles coming out of that vac tube are almost imperceptible. They are like a very fine mist. I have to look closely to see them.

same problem

I had the exact same problem with water overflowing into the CO2 line. If you are supposed to pipe you CO2 line into the intake of the powerhead (instead of directly into the gravel vac tube), I think that some of the suggested gravel vac diffuser designs online are incorrect.

I guess that's how the bubble bounces.. :)
