DIY GFO and Carbon reactor??

[reeferboy83]

I have an old ro/di unit, 4 stage, and got to thinking if there might be a way to mod it to use as a GFO and Carbon reactor? Has any one ever done this? The ones they sell online look like its just two canisters together so would that work with the old ro/di unit? Here is a pic of my old ro/di.

look at the BRS reactors. Cause that is just what they do.

Thats the one I have been looking at on BRS. Trying to do a DIY w/ the old ro/di tho

Shouldn't be that hard, just need a tube to run to the bottom of the canister and some kind of plate to disperse the water a bit. You'll also probably want to run them with separate valves, though as the flow requirements are different for GFO and carbon. Heck, you could even leave that 3rd chamber as a kalk chamber and tie it into an auto-top-off (not salt water!) and make very efficient use of space.

Good idea about the kalk chamber! I was wondering what I could put it to use as! How would make it into a kalk chamber tho? Sorta like a drip method or more like a reactor?

yup just increase the line size to 3/8 like the BRS one and your good to go.

 

[reeferboy83]

3/8 line all the way around?

Whatever you do for the other chambers to get water to the bottom so it flows up, do the same thing but plumb it to the fresh water top off. This will push new water down into the kalk at the bottom of the container and push saturated water out the top. Look up JAustin's build, I believe he runs one like this made out of a single RO/DI canister.

ok....ya Jason lives like 20 mins from me so I'll have to go look t his again. Thanks for the info!

Yes, they do, but pumping water through the kalk won't hurt, and if the chamber is just going to sit there empty, why not get some useful alk/ca supplementation.

To use it for kalk you have to plumb it backwards so that the tube in the center will be the input and let the water go through the kalk and keep it mixed. This will keep the water saturated. I have done this with my top off.
