Co2 distribution

[IamAHill]

Hi I have an Aquascaper 600 with a Oase biomaster thermo 350 with a 2kg fire extinguisher through a diffuser. I also have a little powerhead adding 2,400 lph (tiny little thing but on the lowest setting!).

I've been moving my drop checker around the rim of the tank over the course of a few days and I always have low Co2 in the back left corner. I'm just wondering if someone could give me a pointer on where I should have my inlet, outlet, diffuser and powerhead possitioned.

thanks Andy

I would go as close to the outlet as possible at front of tank, power head right underneath the outlet

Do you mean put the Co2 diffuser under the outlet and the power head?

Yes, I used the same method on my 50l tank and it works well - as long as the CO2 microbubbles/mist are set all over the tank the distribution is good IMO. Under the outlet or opposite side to outlet whichever works/suits best
