Waterflow for a planted tank

Okay then i have a question how do we inject CO2 into the water?

 

Nope. If the oxygen is dissolving in the water, then why does the bubble go all the way to the top? The theory is that the oygen molecule only enters the water when the water's surface tention is broken. This is broken by the bubbles popping at the surface. The best way, IMO, to aerate a tank is actually to have your filtered water pouring into the water from above... i.e like a fountain.

I beleive CO2 is more dissolvable in water than O2.

(Guys, we are running 2 threads now on the same topic- this is getting silly)

 

Yea sorry for getting off topic i just was interested.

 

to get back on track, the water should be well circulated and not stagnant, so you need sufficient water movement in the tank, that said, dont go connecting a speedboat prop to it as you don't want to recreate the niagra falls, the plants can just gently sway to and fro in the tank, not be bent over from the force of the current
