DIY Project High flow DIY reactor - now with video

Is it an Evian bottle? Mine has more of a skinner neck which is what I think the problem is.

Sorry to dig up such an old thread, but I'm looking at possibly building one of these reactors, based around a 20" housing shown here: 20

Did the vortex vein you created work John (@foxfish ), as I am thinking of doing the same thing. Do you think the wide 20" housing shown above will work well, or would I be better with a narrower housing so there is more water pressure pushing the CO2 around the outside of the inner outlet tube?

Hi,
Did you get round to building/using this with success, if so, on what size aquarium (mine's 90x55x53h)?
I'm using a AM 1000 and it's not cutting it for me, having to use an inline diffuser in tandem to achieve targets, tried with original bio balls, empty and now Siporax.
If you did do have you any advice/links?
Many thanks,
Bazz

Charcoal filter cartridge. Works perfect.

OK an old thread but was just wondering if this would work in sump setup. I know the bell diffusion method isn't great but in a container?
I'm thinking there may be a build up of CO2 but surely in a container an equilibrium would be found. Probably other issues I can't see but just a thought.

Sorry need to amend pic

Looking at this again, this system isn't helping with the sumps filtration. I'd guess a very small volume of sump water would be drawn into the container. May be a need for the feed into the container to be from a second pump in sump instead of from the tank return. This then gives issues with two pumps....

Back to the drawing board.

You can easily convert the sump into a high powered horizontal reactor. No need for the diffuser, just create a pocket of CO2 gas on the top.

If you want some help, reach out to me and I am happy to support with design and calculations.

PS. We don't want to hijack this epic thread, suggest to move any follow up discussion to a separate thread or horizontal reactor thread.
