I sew. I used some chiffon material.

ok. i have a slightly different internal filter that im using for the same thing on a different tank but snails and shrimp will easily get sucked into it. i guess ill cover it with panty hose. baby shrimp cant get through pantyhose right?

went to petco today and they didn't have it. is there any way i can check the availability of a product at a certain store location online?

You could just order it online. That's what I did.

i went ahead and got the same thing i have in my other tank from a lfs here. works well imo, spits out a really fine mist of co2 that hangs at the surface

Here's a video of this reactor in action. Forward to minute 2 and watch from there. I think on the video you can hear how the bubbles hit the impeller. Stuckintexas has a DIY yeast concoction feeding the reactor and the CO2 produced by the yeast is a lot. Normally you should not see that many bubbles escaping the magic sponge.

I modified my little pump. I took window screen (grey fiberglass, I think) and cut small pieces and super glued these pieces over the intakes. Now I don't have to worry about anything being sucked into it. I drilled another hole in the side for the air tubing so that it isn't squished at all.

What a wonderful idea! Hats off to Niko!

I also bought this reactor and setup it up as Niko's instructions stated. I then though that it would be even better if I could run the CO2 into a ceramic diffuser prior to dispersion through the Hagen so I found a 1" ceramic air stone that puts out a fine fist, cut one of the slats out of the bottom of the filter, put the airstone inside where the filter used to be with the air nipple coming out the bottom. I hooked up the nipple to the pressurized CO2 and now have a very fine mist hitting the impeller and then to the sponge filter for easier absorption since the bubbles are even finer.

Thanks Niko for the great design. Working with a bunch of engineers, we are always tinkering with left over parts to see how we can modify things.

CO2 in my 15G tall is 5.3 and with a HOB filter and very tiny bubbles coming from the sponge and most don't reach the survace.

I now have mine installed so the output points directly towards the "cage" of my Koralia powerhead, and about an inch away from it, with no sponge on it. Now it spurts tiny bubbles of CO2 into the Koralia where they get blown all over the tank. The little "CO2 reactor" is so small it isn't easy to see behind the Koralia. Right now it is the best CO2 injection method I have used.

this thing is very easy to use and works great. here is a video of mine in action.
