O2 in water

[Esra]

Just a quick question.

I previously had 5G tank that had a small internal filter which did the job great. It had a little intake tube that led outside the tank which allowed it to blow air bubbles into the tank asweel.

Now i have my 120G and i use 2 canister filters. They keep the water crystal clear and move the water around pretty well but i just want to make sure the water is getting enough O2 seeing as there are no bubbles.

Is the movement of the water enough to add in enough O2? Sometime i move one of the outlets up a bit so that it disturbs the surface water but this is quite noisy.

Just want to make sure the little guys can breathe!

The movement of water is just fine. As long as the fish aren't gasping for air, I would not worry. That filtration sounds more than efficient for O2 exchange though. HTH

O2/CO2 exchange takes place at the water surface. As long as there's good circulation throughout the tank, you shouldn't have any problems.

Sweet, I'll move the outputs to make sure i get a good circulation.
Much better than the bubbles as the surface is a lot clearer.

Thanks guys.

Is this planted at all?
