Co2 setup run between 2 tanks?

Co2 setup run between 2 tanks = Done

Hey all.
I'm making a DIY Co2 system for my tanks.
I've decided to go with a 2L bottle, and 1L overflow.
MY question is pretty simple:
Can I use this setup for both my tanks -- ie: hook the Co2 bottle up to a splitter and run a line to my 16G and my 10G -- and have it still work effectively?

Also, I've got the recipe for a 1L mixture (1 cup sugar, 1 TSP of yeast and a pinch of baking soda),, should I double this mixture up for the 2L?

Thanks in advance. O0

 

Well, I just finished my Co2 system.

As stated, I used a 2 Litre, and 1 Litre overflow, and ran a splitter into both my tanks.

Now we wait.

 

Since your two tanks add up to 26gal of water you should be able to do it as you set it up.

Great thing that you two [all plastic] valves for each end after the split to balance the output of both.

Good for you!

I feed four tanks using a manifold but that's with pressurized CO2.

My regulator valves turned out to be a touch leaky, so I had to remove the valves and cap them off so the whole system is air tight now.

They (Who is "they" anyhow?) said it could be up to 3 days before the mixture starts producing bubbles, but other sites I've read said it should start within 1-2 hours.
A little confused.
I woke up this morning, and had zero bubble action, so I looked at the bottle, and there was a bit of sediment at the bottom of the 2Litre. I gave it a shake, and it shot off a whack of bubbles, but then subsided. Now there's no bubble action again.

Did I do something wrong, or is this just the waiting period?
I added 1L water to two cups sugar. Shook til dissolved, then filled the rest the way with water (luke warm), then added a 1/2tsp of yeast and a pinch of baking soda.

Just want to make sure I'm on the right track here.

edit** An added question:: Since I have the tubing split between 2 tanks, should I make sure both lead tubes to the tanks are the same length (for equal pressure)? I would think that the shorter line (in this case, the 10G) would get more co2 due to the shorter travel time.

Thanks in advance.

 

It should start producing within a few hours, I think the three day thing may have been for optimal CO2 production. It may take the reactor a few days before it starts producing its max amount of CO2.

Tube length won't make as much of a difference as water depth, I would measure out how deep under water one end is, and then try to replicate the depth in the other tank, if one is any deeper than the other, all the CO2 will just go out through the shallower tube. Also try stuffing the tip of a golf tee, chop stick, etc. to try to increase the overall pressure in the system. That will give you finer bubble, and the increased pressure will help to correct any small difference between the two depths.

 

Right on, thanks for the tips.
I've leveled off the depth of the airstones (eyeballed really) and I think I'll make another batch of yeast this afternoon if there's still no action.

 

Just made another batch of yeast about 1/2hr ago. This time I made 100% sure to have warm water (not too warm), and I premixed the yeast in a little water before adding it to the bottle.
I'm using
Fleischmann's RapidRise Yeast

fyI (hope I'm using the right stuff).

We'll see in a few hours if we've got a reaction.

 

Yeah, so this yeast, although it works, it doesn't pump out much co2 at all. Its at a trickle really -- not enough pressure to pump both my tanks with a splitter. So I've gone and got some plain old dry active yeast, and just mixed up yet another batch. We'll see how this one goes.

 

I noticed you have some sort of sealant where the pipes enter the caps, this makes me think you might be leaking CO2 , make sure the hole in the cap is way smaller than the pipes diameter , cut the point of the pipe in a V so you can get the pipe piont through the caps hole easily, now use pliers to pull by great force the pipe through the caps hole this way no sealant is needed and the seal is air tight or CO2 tight in this case, if you add a one way valve in the line to the tank you will not need the extra bottle, and this will give you more pressure to the tank

 

She's air tight. I put the sealant there for extra backup incase over time I did encounter a leak. I found out I was using the wrong yeast. I just got ordinary dry active yeast, and it works much smoother. I am however, going to remove the overflow bottles. I've got valves for both co2 setups now, so I don't really need them any longer.

Thanks for the advice.

 

Wow, I didn't know DIY Co2 was possible! Thanks for the tips, as I'm growing plants.

Also, does anyone know if placing the water (or pop) bottle inside of the tank makes a difference? I saw one setup w/ it inside. Why or why not?
