Hi THere,

I've followed the basic idea -
Flow input to a vaccum from a gravel cleaner -
bio balls
sponge at the bottom.
1 bubble per second

Problem is the canister fills with co2 - like an air pocket of Co2 -

Is this because there is not enough water flow or ?

Thanks!

Dustin

Sounds the same as my reactor, so I'd bet that low water flow is the
problem.

Hi Chuck!
Actually I think your site is the one I got the plans from...
So more flow is the solution?

Thanks!

I've just got Dupla reactor 400. It is a co2 reactor.
I've tried the DYI gravel based reactor, but this dupla thing works like a
dream!
There is a plastic cascade that water falls through and dissolves co2 so
efficiently!
And it looks very cool too.
Had to pay a small fortune for it though.

If I have understood you correctly, it's mounted the wrong way around.

Normaly the reactor is mounted at the filter outflow. (Have seen
systems doing it the otherway around though.)

Well I worded that wrong then

The output flow from teh filter, is what is going into the gravel vac..

Its all setup right - I guess there just isnt enough current.

Thanks for the input though

Is this because there is not enough water flow or ?

First I thought of Doing It Myself. But later I found a cheap internal
filter DJ50 (US $12.00).
It has a airline inlet which is for mixing air with water. I am injecting
CO2 in it.

Hi Cannibul!

Actually I did something simular to the pvc idea that hardly worked haha -
So i added the in tank DIY of the gravel cleaner with it - I just dont think
there is enough water flow. I think my options are 1 - take out some of the
media to make the water flow faster in the magnum 350 *its older, could the
magnet need replaced?*

Or run a powerhead directly into the top of the in tank part..

Any Thoughts?

Thanks!@

To adjust for a pre set level:
Drill a 3/16inch hole and put a 1/2 piece of rigid vinyl tubing in
this hole.
Measure down from the top how far you want to have this level be eg 3
inches etc.
Now drill another hole the same size and add another piece of rigid
vinyl tubing , attach a piece of airline to the powerhead's venturi.
Now when the level gets down to that point, the bubbles will get very
fine and the the unit will waste the CO2 since it's now in excess.

If you keep adding CO2(eg too much) the excess will "Burp" out the
other 3/16" hole.

You can also turn your CO2 off this way with out touching the flow
rate or stopping the DIY yeast etc, the excess will go out the burp
tube and when the power head is "off", no CO2 is diffused into the
tank.
I simply plug my powerhead into the lighting timer.
CO2 comes on only when you need it.

Those two adjustments really improve the performance.

filter DJ50 (US $12.00).
It has a airline inlet which is for mixing air with water. I am injecting
CO2 in it.

FWIW, I was doing the same thing but found that I got greater CO2
saturation by running the CO2 line into the strainer at the bottom of the
DJ50 (versus connecting it to the airline inlet).

I also tried redirecting some of the output back to the input by cutting a
notch out of the side of a plastic cup and fitting the cup, upside down,
over the DJ50 ... that was also an improvement but looked ugly.

Of course none of this matters if you're getting enough CO2 with your
setup. ;-) Just an FYI for others who might try the DJ50.

Just run the CO2 into the intake of your Magnum. They make great
reactors.

You should have had enough flow with the Magnum to make the external
reactor work. What size PVC did you build it out of?

1/2 inch

Thanks
