Woo-hoo! This thread will never die!

Or rather it will - when stingy people disappear. That would be about the same time when the ultimate tool (a hammer) cannot find an application any more, haha!

Joking aside I have to say that I have an interesting observation about this diffuser. It's about algae and it's simple: BBA and Cladophora happily develop on the top side of the sponge. Not every time of course, but I've seen in about 3 times now. So much about fighting algae with high CO2.

Other than that - I've had one of these diffusers in a heavily planted 55 gallon tank working for more than 2 years now. No cleaning, no maintenance.

One if these reactors is enough for a 75 gal. tank with tons of light with a bubble rate of about 2 bubbles per second.

Without a sponge the tiny bubbles fly everywhere and make the water look not completely clear. Plus a lot of them get wasted. If you add a sponge in front of the same pump you will need to reduce the CO2 bubble rate about 30 to 50%. Impressive savings.

This is so true! I just put on the sponge and had to turn down the co2 by half because the drop checker turned yellow in a few hours and the fish were gasping. This has to be the best diy ever for co2 diffusion. Thanks again for posting this.

I just recently switched my filter to the outside and it's a huge difference! I can't believe what I was missing when I first purchased this. Can't wait to hook up my pressurized CO2 setup tomorrow when I get my On/Off Valve!

does this work with diy co2 and do they still sell the mini elite hagen at petco? shipping on the site costs as much as the filter itself!!

I was just chatting with a PETCO rep about the shipping, they said "but the item has been discounted already.." and "yes, the shipping cost has been decided upon the product itself." Luckily, I found where they carry it within a couple miles of my zip. I'd still like to know if this would work with a DIY contraption, although even with check valves, it seems the filter could 'suck' the mixture into the tank. I'm a newb though, admittedly.

Yes! This works with DIY CO2 reactors - self-made or store-bought!

You will save a bunch if you never buy a pressurized CO2 bottle!

I save even more by just blowing into the tubing and disolving the CO2 with my ingenious reactor. So far I've saved like $20 for just one year! Takes me only 7-8 hours every day!

I got so used to blow air for hours on end that I started to make very cheap furniture too. Here's a chair I made. The two paper bags cost only $0.99 each!

Default Re: Tiny super efficient CO2 reactor

has anyone tried just running the co2 line into the venturi? thats how i have mine set up and the bubbles it produce compare to the ones on youtube are considerably smaller and doesnt float straight up right away (though it is not a cloud/mist of bubbles). Im thinking about getting another one for another tank and run it the way everyone is doing it (co2 into the intake then to the propeller) to see if there is a significant difference

Hi everyone - I tried this out and it seems to work so far. I posted a video of the entire process. Enjoy!

I just run my tubing into the middle of a giant sponge in my sump which does an excellent job at diffusion the co2
