my version of the diy co2 reactor

finally got my co2 equipment from "premium aquatics" and got my materials for my reactor ready. found a local company that carries clear pvc, so i went to pick up a piece and found they only sell 10' sections , and at $7 a foot i didnt want to buy a whole 10 footer , my original plan was to use 2" but when i found the supplier had a piece of 1 1/2 " i grabbed it , and to make it even better he gave it to me free! hopefully when i step up injection rate it will continue to work well. right now at 2bps it works like a champ... and i think it should keep working as planned . if not i have ball valves which i can adjust flow rate if needed .

so here are some pics....

Every elbow you put in that water return line increases the back pressure on the canister filter pump. Since those pumps produce very little pressure to start with this can be a problem - reducing the flow through the filter excessively. For that reason it is better to use as few elbow fittings as you can get by with. You have 6 elbows. It looks like you could easily reduce that to 4. And, by using hose, with large radius bends, you could reduce it to 2.

I am not running a canister . I am running a sump ... hence to possible need to reduce flow via the ball valves . Flow restriction will not be an issue for me....I am moving about 900-1000 gph the pump is rated for 1450 gph but my tank is 6' to the top .
And with the unions I have in the system I can add another chamber pretty easily or even increase the clear pipe diameter if needed..

In my opinion, you're going to have better results with a large diameter tube for the chamber. If the chamber is too small it will just blow the co2 bubbles right through without leaving them time to dissolve. Hopefully the length of the chamber will help with that.
