Works and is well made

Comments: I'm not sure why some have found this product to be cheaply made. It is WELL made. The pieces fit tightly together, and I dropped mine (full of water) on a concrete floor without any damage whatsoever. It is nicely designed and works like a charm, but I don't recommend it for a small tank because of its footprint. It would be great in a big tank.
The instructions recommend a flow rate of about 100 gph. I would recommend that be the max or even a little less so there is more time for the CO2 to be dissolved. I don't recommend a Mini-Jet pump as these pumps ALWAYS fail to restart if there is a power failure - perhaps a Maxi-Jet 400 with a flow regulator. The reactor produces a great vortex to help dissolve the CO2. And by the way, the photo is correctly shown - it is right side up. I have read where people have said this is upside down. You want the vortex chamber at the TOP.
The product allows a multitude of ways to position the components since they come apart for easy cleaning. For $19.95, you can't go wrong, and it looks more professional than a DIY reactor. Very cleverly made!! You can connect a pump to the reactor with the tubing used for a gravel cleaner. It also comes with a directional output you can add to the bottom container. The green color blends in well with the plants. The only negative I would say is that it has 4 suction holder "points/nubs" but only includes 2 suction cups. They should really supply 4 since there are 4 holders. Other than that, it is excellent.
Also Using With Ozone

Comments: The is a very, very, cheaply made piece of plastic that works perfectly as an ozone reactor. I am using mine as designed for CO2 with the ozone coming in through the top. I removed the media in the bottom, cut a small sponge filter to fit the bottom 1/2" and refilled the compartment with carbon.
FYI - I found that in order for this to work properly I had to also use an air line check valve and have some way to regulate water flow.
GREAT FOR OZONE!

Comments: I know it's made for CO2 saturation, but I bought this little guy as a makeshift ozone reactor. I didn't want to ruin my $300 skimmer by injecting ozone, so I took a gamble (albeit small) and bought this to see if it worked. I'm running this inline with (in order) a Tetra Whisper 40 air pump, an air dryer by Ozotech, the Ozotech Poseidon Jr. ozone generator, this reactor, and a Rio 800 pump. The picture above has it upside down, as air and water enter through the bottom to creat the vortex. It's not sealed so it has to go in the sump, but otherwise it's a great buy for only 20 bucks!
Best reactor for the price

Comments: Simple, cheap, and it works extremely well.
I have several types, including a membrane diffuser.
This is the one I will am buying more of.

Comments: First off, let me say that this device is extremely cheaply-made. If it cost more than a couple of dollars to manufacture, I'll be very surprised. That said, at $20, it is probably the most cost-effective way to boost the CO2 levels in your planted tank. Powered by a DIY yeast-and-sugar-water CO2 generator and a mini-jet 404 water pump set to the max (108 gph), the CO2 level in my 20-gallon planted tank is 12 ppm, which is more than adequate. Like I said, it works. It's inexpensive. Just handle it gently. It wouldn't take much effort to crack it. I split an elbow while installing it, which is why I only gave it 4 stars.
