No frustration here !
As Crazy Loaches said, there is almost no difference:
If I fill my reactor with 3" of CO2 the same thing as yours will happen, but if I start the circulating pump the CO2 will dissolve very very fast.
Having the CO2 injected on the inlet from the pump helps creating small bubbles as well.
My initial intent was NOT to have this big pocket of CO2. I am using a PH controller, so when it shuts close the solenoid the PH will not drop, as there is no more CO2 to dissolve.
If I was using the "massive CO2 pocket" it will keep dropping to a lower value than the one I choosed.
I am not trying to get a big vortex, just a tiny small one is enough (u can see it in the vids) to reach the point where all of the gas is 100% dissolved, no losses at all.
Even if some of it is not dissolved at first pass, the gas is lighter than H2O so it stays in the center and it's sucked by the recirc-pump and "chewed" by the impeller (I also thought about using a needle-wheel
) and reinjected in the circuit.
Not a single bubble is going in the display tank ( even if my tank is ugly).
No mis-understanding here, all DIY is good to share, especially good ideas !
BTW, I've been quite often to Turkey 2 years ago.......
I use this one as well on an other forum:
Bender rocks !
