Ok, so I took it down yesterday, hooked up the brass hose barb up with some teflon tape, and it was sealed good to go. SWEET! Now my only thing is, the reactor is about 2' long, filed with biorings, I'm injecting into it at about 2 bps. The thing is, i'm getting a few bubbles out the spray bar, and plants dont peral at least for 3 hours after the lights come on, it seems about 4-5 hours after they are in a good swing. I dont have any very heavy perlers (ricca, ect).

How can I get 100% absorbtion of the CO2? it seems i'm wasting a little on every bubble. Here is my reactor design. I took the rexgrieg design and modified it a little bit. Now i'm thinking of selling it in favor of a 3' reactor.



Excuse the silicone around the brass hose barb. I attempted to seal it quickly with out taking it down, and it well. Didnt work. But here is a picture of the intake side. Water comes in the 90* elbow, and out the straight top.

You say that the water enters at the 90o elbow end, where the CO2 is injected and exits the straight end. Does your reactor sit with the bend at the bottom? In which case simply flipping the reactor round so the bend's at the top will help enormously.

If you do you usually have the input at the top then the only thing I can suggest is reducing the flow rate through the reactor. When my Ehiem is at full blast it blows bubbles out of the reactor and mine's about 2.5" diameter, when I turn it down a bit I don't see any bubbles coming out in the outflow.

Water comes in the 90 And out the straight correct. making it with dual 90's would have been preferable, but i couldnt do it. The way it's set up is so tight already. I'm not even sure i could go larger on the pvc size, maybe just longer? I dont see many bubbles because i have slowed the flow.

Now my next question. I dont see much perling until about noon, this is 3 hours after the photoperiod begins. And even then it's just "false perling" like if a plant is cut or something, but i do eventually get the perling. I dont have the best "perling plants" but i have Cabomba, Bylaxia, Vals, i think 2 melon swards, marsilia, stargras, java moss, spiky moss. and a few others.

WHAT IF, i were to extend the pipe before the 90, I could extend it another foot maybe two, and that'd give me an overall length of about 3-4'. I could inject at the far end of the straight pipe and it'd have about 3-4' before it was going back into the hose and into the tank. Any thoughts on this?

So I built the reactor following Gomer's plans in the first post. I've got the CO2 going into it and have the reactor set up on the outflow of my Ehiem Ecco 2232. However, I have one problem. I can't get the CO2 to go into the reactor!

I have the pressure on the regulator turned way up and the needle valve completely open. I have a solenoid, and that is also on and open. Unfortunately I can't tell you the exact pressure coming out of the regulator because it seems that my regulator is bad and doesn't want to display neither the cylinder pressure nor the regulator pressure. If I turn the outflow on my filter off then I get about 1 bubble every two seconds, but if I have any water flow at all I get no bubbles and water starts to come back up the CO2 tubing.

Any ideas/help?

P.S. - Just realized that while I have the in/out on the reactor hooked up correctly, I have the water coming in at the bottom and going out the top. If I flip it around will it fix my problem?

Ed - First i gotta ask, which side do you suggest hooking the reactor up to? It's currently on the discharge line. Second, if i flip it over with the 90 on the top, and inject there, then i'll have to run a hose down to the bottom of the straight piece so the flow would be reversed of the injection.

As of now the water goes in the 90 and out the top.

OH NO!

The water and the CO2 goes in from the top and comes out at the bottom.

This causes the micro bubbles to be carried to the bio-balls and coaxed to dissolve , while the larger bubbles rise to the mouth of the water inlet and gets pushed downwards vigorously breaking down into smaller bubbles .

I'll see what i can do. I'm going to have to figure out ho to work around this 90* i have in there, but i think i came up with something. Just gotta maybe switch some hoses around. Now I wish i had another set of hoses.

Hi,

so is there a general formula for the length of the reactor compared to the power of the cannister?
It seems like if the cannister is extremely powerful, even with the proper orientation (in 90 degree elbow, out at bottom), it will blow bubbles out of the spray bar.

I have a renaissance cannister that is powerful enough to filter a 120gallon aquarium (i don't know the gph, but it was much stronger than my eheim 2227, which I returned).

How do I know how long I need to make my reactor? And if I need to make it longer, am I only adjusting the clear tubing in the center (going by the DIY plans stickied).

Btw, I have a 55 gallon with the cannister mentioned, and I'm either going to do the reactor and make it woirk properply. Or go easy style and get a glass diffuser rated for my tank size on ebay.

Pros and cons going wtih just a glass diffuser in tank?

Thx all!

this is probably a stupid question to all of you pro's but what is the role on an inline reactor in a filtratyion system? aka what does it do? is it like a diffuser? breaks up co2 to evenly distribute it into your tank?

Dissolve CO2, you can run 1 on just a pump, it does not need to be on a cannister.

For PH, I think width is also a very considerable factor, the wider the PVC, the more water will slow down, preventing the bubble from just shooting out the outflow.
