Would This Reactor Work On Diy Co2?

[ebrcknrdg]

Im really up for making this reactor but i dont know if my 2 liter coke bottle and nutrafin will have enough pressure? Does it need pressure for it to work seeing as it has the pump attached? Not 100% how it works

scroll down to bottom of that page to see reactor

anyone?

is the idea of the reactor to help the Co2 dissolve?
as I have been thinking is it not possible to have a Tube facing down in the water, and there is an air pocket inside the tube, half the tube full of water (if this makes sense)
add to the bottom some sponge so the Co2 has to build pressure inside the tube then be forced through the sponge,

So while inside building pressure it is being absorbed by the water,
then split into small parts by the sponge (or something similar)
then the process starts again of building pressure,

Or am I just speaking total crud

erm i dunno but ive seen a few of these so they must work

What you are doing with a CO2 reactor is injecting the CO2 at the bottom of the reactor, against the discharge of your filter. The bubble rises slowly up through the media against the current, being dissolved all the time before finally settling at the top of the reactor where it is thrown around for virtual 100% dissolving.

I am not sure, but I would have thought that if DIY pressure can run a ceramic diffuser, it should be OK in a reactor. Although you should always use an NRV, make absolutely sure you have one if you go for this type of set up.

The main advantage of the reactor, IMO, is less hardware in the tank and no CO2 bubbles blowing around the tank, but it is still not as efficient as a ceramic diffuser, despite dissolving the CO2 almost 100%.

So how would this work exactly with an External Filter?
simply make the bubbles to where the siphon is happening? so they get sucked in?

this is simply a circuit for the bubble to run? or am I wrong,

Sorry ebrcknrdg I didnt mean to hijack this

That will work perfectly with DIY co2. I'm using a cheep $8 pond pump with a similar concept with my co2.

could you try and explain (simply if you can) how you have your reactor set up? This one is going to cost about £25

 

[ebrcknrdg]

would it be easier for me to put the co2 tube into the outlet tube of my filter like this?

Is this just the same or wont it be as effective?

I was able to find a pump similar to this http/www.petsandponds.com/securestore/c2...16697986.2.html at princess auto for $8. I just stuck some 3/4 tubing over the output nozzle used the old blue sponge from my canister and a little air stone.

Here's a nasty little drawing

it works pretty good for me in my 29g with 2x2L diy

It will be very effective but you have to be very careful or your filter can suck the contents of your diy co2 into the tank. I've also heard that the co2 can make the plastics in your filter brittle ( true?!? I have no idea but I don't wanna trash my nice new filter) It can also make your filter quite loud from what i've read.

hi, its not actually going to be "in" the filter, just in the outlet pipe. The hole is drilled in the side and the tube pushed through with an airstone on the end. I thought air stone diffusion wasnt much cop or is it more effective because of the water flowing past it?Em

Thats a whole new concept for me! How are you monitoring co2 and do you find it to be quite stable? Sorry for being dumb but what is 3/4 tubing (im from the UK) What is that little stick thing the airstone is on?

 

[jspence1]

the 3/4 tube is just some 19mm hose (any hardware store should have it for about $2.50/M) that I had in the garage and it happened to fit nicely over the output of the pump. the stick is the airline from the co2. I'm using a drop checker and I'm able to keep it in the "green" by changing 1 bottle every 10 days.

Sorry for al these links but i think ive found something so simple? I have the eheim external filter and this is how this guy has hooked his DIY co2 up to it

I dont get this bit though "I used one of the nipples that come with the really thin air hose to splice it with the thicker hoses" If look and understand please explain!

 

[ShoC]

I dont understand how that works to be honest, the picture you supplied,
I would have thought it has to be inside the tank,
With Co2 being pushed into the gravel Vac and the water from the cannister going inside the Gravel Vac also so they mix in the tube.

that looked outside of it to me,
and the water was then going into the cannister surely thats would be very bad for the eheim.
and it would make constant noise at the Co2 passes through the motor, yes it would be effective but To damaging I think.
