Internal inline reactor ... providing DIY CO2 for larger tanks

I have been using DIY CO2 for about a year on my 100 gal tank. I went through many different designs, bottle sizes, bubble counters, powered reactors etc and finally found a good solution.

I am not recommending DIY CO2 for tanks of this size. Pressurized would be better... less maintenance, easier to automate. But for those of us with low to medium light tanks, this is still a very inexpensive alternative. If you are intimidated by high pressure steel tanks, regulators, needle valves and adaptors, and don't mind mixing some sugar and yeast with water once in a while, this might be worth a try.

Nothing new here really... just a design that works well for me. A little more refined on the left, and simple and straightforward on the right. I used gravel vacs for the reactor pieces.

I was thinking of doing that, but I was wondering how the water flow was in this type of setup? I have my spray bar from my XP3 extended down into the water about 6-8 inches from the surface with the holes pointed upward. There isn't any agitation, but pretty good circulation. With just one XP3 in my 46g do you think the flow would be alright...for the fish? I do have an aquaclear 200 for mech-filtration also.

40g AGA Breeder: Pimp# 44: Eheim 2026; Anti- Filstar; CLTT UV; 3 wpg PC, pressurized CO2. GATA! FTD!!!

You can still keep using the spraybar, just shifting it down closer to the bottom. It's really just a bulge in the filter outlet hose...
