Does everyone else use the same recipe?
What do people recommend for their co2 system during the night when the plants aren't absorbing co2?
I use the identical setup with two 2litre's and I am able to achieve excess amounts of dissolved co2
in my 75 gallon.30+ppm. For the people that will ask the next question, diffusion method?
I use a Korilla powerhead with the tubing run into it from the bottom through ahole I drilled.
The propeller in the korilla chops the bubbles up so fine and fires them out at 240 gph.
And if you point it just right you will never have a problem getting the desired co2 level.
And if you have fish in your tank you should turn off/redirect or allow co2 to rise to the
surface by turning off the powerhead,because a build up of unused co2 will become deadly
very fast. My choice is redirection through your typical bi-directional valve.
Hope this helps!
