CO2 Reactor 500 1-5/8" x 3-3/4" x 2-1/4" high; up to 125 gallons
About 90% dissolved
About 90% bubbles dissolved at 2-3 bubbles per second. The tornado chamber is just a little too shallow as the odd bubble escapes before dissolving. But, 90% is still an A- in my book.
A taller chamber would be more effective but then it wouldn't fit so perfectly in the corner of your tank.

Reactor 500 does a fine job.
Reactor does a good job. Plants really thrive with the co2. I have a 75 gal tank. I purchased 3 val plants and now have 20 plus and more coming. Other plants doing well also. Bearing in reactor will make loud noise and sometimes you can get it to quite other wise reactor needs to be replaced. Reactor usually lasts for 2-3yrs. Doesn't dissolve CO2 at more than 60 bubbles per min.Foster and Smith has the best price.

Good, but not durable
This unit works very well at diffusing CO2, no doubt about that. My issues were in the design. First, the power cord comes out the bottom of the unit, making it very prone to flipping and tilting if the little rubber suction cups aren't properly stuck to the glass. Which leads to the other problem. The little suction cups are VERY little, get very brittle and lose their suction ability in a short period of time. Once that happens, the unit flips and tips and becomes far less efficient at dissolving gasses. I would recommend this unit, but only if you can find and keep a good supply of the cups.

This product does not work!
After receiving the reactor I installed it in my 30 gallon tank and connected my homemade CO2 device to the reactor. Immediately the reactor started spinning the CO2 in a vortex expelling any CO2 that was introduced into the reactor from the bottom. I thought to myself "Ok that is a big waste of CO2 but that I would give it a try for a few weeks". After 2 weeks and testing the water, I found no appreciable amount of CO2 in the water. The big problem of course is that the vortex just spins the water around without mixing it into the water. What they need to do is make this into a blender of sorts. A impeller is need to actually mix the CO2 and water together as it enters the chamber.
