Co2 Reactor

[plantbrain]

Yes, all the CO2 is dissolved by the time it gets to the filter.
so that is not an issue.

You can place the CO2 gas input anywhere along the line up to the reactor or in the reactor but think about it.

Why would it not be a good place to put it on the bnottom of the reactor that's always full of water etc?
1# Leaky leaky.
2#You can purge the tube of any air or CO2 etc if you need to since gas rises and get it going right away.

You can also add the gas at the input of the siphon tube qwhich I prefer since this creates positive suction pressure rather than back pressure on the CO2 line. This will remove any need for a check valve or potential of leakage, gas or water etc.

Add the CO2 input anywhere else and it will create backpressure of some sort.

So if you add a 3/16" rigid tube into the reactor tube at the top and seal it good, then plug it with a removalable plug, then you can purge the reactor if you need to and always have positive suction by feeding the CO2 into the intake.

That's the way to do it.

I'll get the page for the DIY method up here, give me a few minutes

Avonlea...I was in the assumption that the reactor goes on the OUT side of the filter...so the co2 would never go into the filter in the first place to cause the air pocket...what i meant by bottom was that it went in the bottom of the reactor instead of the top after the filter.

You know, I was laying in bed last night thinking about my post. I realized that I was a bit confused. I understand now.
