Diffuser for homemade CO2

[i_am_the_walrus]

I'm setting up a 45 gallon planted freshwater tank, and am going to use the homemade co2 yeast/sugar/water trick.

Any suggestions for a diffuser that works well with a homemade co2 device?

Thanks in advance.

In the filter. It isent the best for it, but it works.

Yep, let the impeller of the filter chop up the CO2 bubbles. If it were a pressurized system, I'd recommend an external diffusor, but with a home made CO2 system, the pressure just isn't constant enough.

So just place the CO2 outlet tubing next to and below the filter intake? I have a filstar canister, in case that matters.

Thanks again.

Iv got a filstar too. I just place the tube in the intake. It works. I may get a Hagen ladrer later on though to help save the rubber seals in the canister.

A small plastic (clear)bottle (as a bell diffuser) works well costs nothing and saves your filter. Attatch to the wall with suction cup (thermometer holder) run from the bottom co2 line into it. Make sure its a narrow neck bottle to prevent fishies from getting inside. Make a tiny hole at the top so co2 can eventually escape. done.
