Refering to This.

When he says
"Diffusion Methods
1. Line directly into the intake of your filter,"

What does that mean?

 

[bgzbgz]

It means sticking the co2 tubing (where the co2 comes out of) into the filter intake (where the water goes into the filter).

That's it. That's what I do on my 10gal with AC HOB filter and pressurized.

So would that auto regulate the ammount of CO2 so my fish dont die of asphixiation?

 

[bgzbgz]

With diy co2 I doubt that you will ever produce enough co2 to kill your fish. But either way if theres too much co2 in your water you will notice your fish hovering at the very top of your tank (closer to oxygen) breathing rapidly like thier gasping for air.

 

[bgzbgz]

Oh and your cannister can not regulate the amount of co2 in the water. With diy co2 the only thing regulating how much is in your water would be you yourself. The best way to achieve this would be to mix the proper amounts of yeast and sugar in the bottle. In other words less yeast = less co2. But again I doubt you will have too much co2.

Mkay, thanks

You have very little control with diy CO2. On pressurized systems, you completely control it by the flow rate you set it at via the needle valve.
