Co2 diffuser placement

[Philip99]

I recently got a pressurized co2 system and I was wondering where the best spot for the diffuser would be?
Here is a picture of my tank

It appears to be in the center directly under the flow of the HOB output. If so, I would leave it there. That way most, if not all, of the CO2 bubbles will get caught in the current and distributed to other parts of the tank. Anything you can do to extend the contact time of the CO2 bubbles.

First off, your tank is awesome. Secondly, I would suggest having it down as far as it will go in the tank (touching the bottom) and do as Fresh2o has mentioned above. Then you should be good

If I wanted to move it to the side, could I just place a power head about it to help distribute the co2 with in the tank?

I actually did the same thing you just said- I moved mine to the side of the tank where its not as visible and placed a water circulator at the top of the tank directly above it so the bubbles will float all the way up there then get sucked in and spat out all over the tank. The little bubbles looks kind of nice and natural going through the water And your tank is AWESOME! What is that large leafed plant in the mid-ground?

Well I feel bad for just giving my 2 cents and not complimenting the tank layout. It looks great!

The plant I think your talking about is Hydrophilia corymbosa var 'stricta'

Thanks it looks great. It must have an awesome parent

Alright here is an updated picture with the power head located above the diffuser

Can you skip the diffuser altogether and just run your co2 line directly into the powerhead?

Yes you can, but the diffuser + powerhead break up the bubbles more than just the powerhead will.
