Which Diffuser Is Best?

[DaveW]

I just received my JBL CO2 set today.
I'm planning on feeding it into the inlet of my filter, when I get a bubble counter, but at the moment I will use a diffuser. I have been using a Nutrafin CO2 ladder with a diy mix. And I was wondering which diffuser is the best, the one with the JBL set or the Nutrafin ladder?
I did receive two extension to the JBL one, but I think that would be to much. With the extensions it would be over a foot long, my tank is only 18" high.
Anyway, which one do you think I should use?

Hi

My tank is the same hight as yours (180L). i have the jbl defuser and used both extensions that came with it.

Do you get any bubbles coming from the top, or does the co2 dissolve totally?

i get bubble coming out the top thats why i extended. save me money hopefully unused gas tends to build up in the top until theres enough pressure to squeeze one out!

It's unlikely that all C02 will dissolve with the JBL diffusers so if you want better value out of your C02 (which most people do) then switch to some other type of diffuser, preferably with some type of ceramic plate which make the bubbles tiny.
