My goal at the moment is to improve the way i dissolve co2 gas into my aquarium.

I'm currently using a cal aqua inline diffuser and do end up with undissolved co2 entering the tank as medium sized bubbles which raise to the surface and are lost.

In not such an elegant solution, I am considering extending the pipe between the the cal aqua diffuser and the tank to prolong the contact time between the water and the co2 bubbles
or possibly connecting a reactor to the output of the duffers,

maybe that is just an over kill and i wont need the inline diffuser once i've built my own reactor...

what do you guys think?

Hi kev,

Extending the time the c02 is in water will help dissolve it, but you will lose some of the misting effect as some mist is lost in the longer dwell time.......

Many ways to improve available. Have you considered the mist/diffusors or a needle wheel pump setup? Reactors also work well.

What size tank, filter, pump, etc to help us size properly or advise on a method sufficient for the tank size and overall config and goals........

Later,

Try cleaning the diffuser more often, say soak in Tilex for 5-10 minutes, rinse, add to dechlorinator, and return.

This should result in better bubble sizes.

Also, adding mist pre filter might work okay also, just as long the bubbkles coming in to the filter are not that large. You'll lose the mist in the tank though.

just a question from my side: we don't have tilex in the netherlands. I went to their site and noticed that they sell a variety of products. which one is the one you are using? may be I can find something similar.

greets,

I'll see if i can find that product locally, not too familiar with it but from the website there are a few different formulas, does it matter which one i use? possibly the mold/mildew bottle?

by the way, I've soaked the diffuser in 100% bleach for 2 days and it hasn't made the surface pad white. I guess that means the diffuser was really over due for a clean...
