Another Calcium reactor question (2 Viewers)

[Guest]

I am designing a calcium reactor that will send the effluent water from the top of the reactor to the tank.

My question:
Does CO2 accumulate at the top of the calcium reactor typically?

I will be sending the CO2 into the pump intake, but it seems to me that bubbles will end up at the top of the reactor. I just want to be sure that the CO2 will not just escape with my effluent going to the tank.

As long as your co2 is in the water you should be able to dial back the reactor enough to get the water pH low enough to dissolve the media. You could also add a hose to the top where the exess co2 can go back to the pump intake with the co2 from the bottle. Just use a T for it.

The problem with the idea of having an extra hose to suck the excess from the top is that my pump will be internal. If you look at the picture of the reactor I am making here:

you will see the issues I am worried about.
The pump sucks water from the bottom of the reactor, and the pump is at the top. This means the pump will blow the CO2 into the upper area of the chaimber. Please check out the picture. There is another link to the reactor with a better pic here:

You have to select the KNOP S IV under the technical devices tab.

I know this design looks like a pain in the butt, but it is going to look sweet. I am going to make it look like my PM skimmer, then make an effluent chamber that looks like the waste collector. Everything will be symmetrical under my tank.
