eyebeatbadgers, man that is a new one.

taoyeah, Rex's is fine, but I would reccomend Green leaf Aquariums who is one of our sponsors here on these forums. You can see there banner from time to time on the top of these forums. Orlando is the member here to speak with. I am sure he can help you out.

Translated text: "the design rex uses is very good, and simple, which is attractive for many. it's very cost effective too, which is a plus.

you may also look into the misting technique, which is also pretty inexpensive, and involves a needle wheel pump or a modified power head.

most people on this site also prefer reading complete sentences. you are more likely to get replies this way.

hope this helps, dan"

LOL my head hurts now!. bed time.

P.s. Tom Barr has a nice one on his site to http://www.barrreport.com/articles/3...2-reactor.html

IMO a little more complicated then rex's but i have herd good things about it once you figure it all out.

EDIT:
P.P.s i built Rex's, only modifications i made was the last "T" was removed and replaced with a 90deg turn, so no need to cap the end.

I built one 2x12 with polycarbonate tubing , you can find them where they sell plastics and sell them by the foot it stays clear you can drill and tap them and the rest of the parts you can find any where like Home Depot, I even threw in some small bio balls it looks like this one {like first one listed in the fourm}:

you may spend a little bit more but it was easy to built

here's how i made mine. its based off the rex design, just a few differences...

here's what i did. here you can see a pic of the fitting where the co2 line will be attached to



this makes for a clean design, but the problem is, as stated, that by insterting the co2 at the edge of the pvc piping, the co2 bubbles will have a tendency to run along the side of the pipe, avoiding the incoming water and will not get dissolved proplerly. so, what i did was add another fitting on the inside of the pvc fitting. thing is, you cant thread a fitting in from the inside. SO, i filed down the threads from the inside and forced in the plastic fitting you see here (1/4" barbed fitting).



this fitting is fitted with a piece of rigid plastic tubing that stops about halfway into the tee. here you can see the reducer fitting with barb fitting placed into the tee connector. the co2 will exit in the middle of the reactor and meet the incoming water to get dissolved effectively.



to avoid any leaks, i sealed the whole inside of the reducer fitting with silicone



here's a pic of the tee connector with the reducer fitting and the barbed connectors



and here's the completed assembly, in the cabinet.

How about one of those vortex powerhead type reactors, how do they compare? A tube with a cap and a hole drilled at the top for co2 and another hole drilled on the side at an angle with a powerhead connected to it creating a vortex/tornado effect as it dissolves the co2 into the water.
