Weird problem with DIY CO2

So I decided to build a do it your self CO2 kit and made it out of 2 juice bottles and third soda pop bottle to catch run off. I have it going for a day and I am having an issue.

Intead of hooking the tube to a ladder or a difuser, I dropped the hose under a giant piece of driftwood, figuring that the shape of the wood was perfect for a bell scenario. I got everything set up and going but my bubbles will not come out when the tube is on the bottom of the tank. As soon as I lift the tube up (about halfway up the tank) bubbles will start coming out, (pretty quickly) but as I lower it back down, the bubbles stop. (so if I were using a ladder I would be in business)

What do I do? I am using the 2 cups of sugar and activated yeast-just went and got some champaign yeast today- It seems as if I don't enough power to push out the bubbles.

Is it possible I am leaking around the holes and should seal them. I drilled the holes small and had to use pliers to pull the tubing through, and the tube is full of CO2 so not if sure if that is the problem.

I really want to vent the co2 under the wood, since I have seen such bad press on the Haggen system. I am tempted to put a sealant on the tubes and switch to the supposedly more reactive champaign yeast, but I don't want to be premature- I have been set up for 26 hours.

Sounds like a leak in your system! Yeast+Sugar+Water can create enormous pressure, so that isn't the issue. Clamp the hose completely shut, and wait an hour and see if a lot of pressure builds up in your bottles. I bet it won't and you have to go find the location of the leak.

I just don't get it why people don't use test tube stoppers.... so much easier to work with. No drills or sealants.

I totally agree with dscmeh. It's most likely the tiniest leak in your bottle cap that is ok until the pressure of water in your tank exceeds the current pressure in your tube.

I used the ladder with no problems too. where is the bad press comiong from?

No I didn't seal it-I read in some DIY articles that if you made the holes smaller that you didn't have to use sealer.
Not sure what test tube stoppers are, never saw any right up on them in the DIY guides.
Seems like it should be easy enough to fix, just slap some sealer around the caps and try again.

I've heard nothing but good things about the Hagen ladder.
Certainly it is better than a bell system like you want to do with the driftwood.

Have you considered buoyancy issues with pumping CO2 under the wood?
I suspect it might float or tip and spill the CO2 bubble.

Test tube stoppers are rubber "corks" for plugging test tubes. They may or may not have a hole in them for inserting a tube.
You should have seen lots of them in school.

The way you would do it is one test tube size 3 (or was it 5?) with a single pre-drilled hole on top - the hole is exactly the right size for a snug, leak-proof fit for airlines. On the third bottle - your runoff bottle - is a two-holed test tube stopper. One for the in line and one for the out line. The out line would then connect to your diffuser/ reacter.

The Leak is probably at one of the Tees....What type are you using: some of the airline tees aren't worth a flip for this....

Y connectors wouldn prolly work better than T connectors in this case too.

Well I have it all sealed up and just added the yeast and we will see what happens.

As far as the driftwood goes, it is actually more the size of a log than flat driftwood, except that instead of being flat bottomed like many logs, it is domed and sits on four small leg like branches-you could easily fit an average size cereal bowl under it-I am guessing it weighs about 15-18 pounds.

I hope this works as a diffusion method, right now I got about 5 bucks and 4 hours into this. So far the most expensive part occured when my wife accompanied me as I went out to buy champaign yeast. After about 10 minutes in the brew supply store, She decided she wanted a home wine making kit, to the tune of $150. I said no problem, as long as I can upgrade my light fixtures.

just be patient with your DIY setup until it has enough pressure to overcome the water presssure pushing up the tube.

Also if you're going to set up a bell system it could be worth your while making sure you have some decent flow around it (or through it) so you don't end up saturating the water underneath it and getting none anywwhere else!

Good luck!

On the Gatorade bottles, the caps are wide enough to fit the tubings in. I put out 2 bottles straight through to a 3rd bottle that's empty. From there it goes to the ladder. I haven't had any problems with the DIY system. I believe that the Gatorade bottles are pretty strong enough. 3 tubes in a Gatorade cap fits well. And I don't use rubber stoppers. I drilled the holes smaller and the lines fit in snuggly.

I wanted something that wouldn't shift and break seal if I wanted to pull off the hosing or twist the caps, so I drilled small enough to wedge an in-line air tube connecter in the cap (had several lying around and they only cost about $1 for 8 at the store). Didn't have to seal it and it doesn't leak a bit, and I like the fact that I can remove the tubing and replace if I need to change lengths without breaking any seals.

Something so expensive and addictive HAS to be illegal. I'm just waiting for the police to break down my door and confinscate my fish food.

well I went to the LFS and they had the complete Haggen system on clearance, ($10) so I picked it up for just the ladder. Hooked it up to my DIY and after about a day the bubbles are now rolling all the way to the top-although really really tiny when they get there. So I am officially up and pumping. Next on the list of 2 do's is wipe out the black beard algae that is forming on the drifwood and upgrade the lights.
Who knew I would have a 2 do list on a fish tank!!
