I am running close to 3 and still getting a greenish blue I believe hard to really tell since my glass bad a green tint.

I have a Few Amazon swords one got huge so might be hogging all the co2. I could be making that up as well.

Haha ordered some as well. Bookster and Fresh are making me poor. My kids just wanted a gold fish from the carnival which started this mess

Yes. Volume wise, 1 gallon of Metricide 14 is equivalent to 7.5 bottles (500 mL) Excel. Strength wise, equivalent to 15 bottles of Excel.

CO2 Reactor Lesson Learned

Quote:

That being said, there is a noticeable caveat with DIY CO2. When you first start your batch, the entire CO2 fermenter (and any gas separator you use) will be filled with atmosphere, which is 80% nitrogen, 20% oxygen (and much smaller percents other things), which is all insoluble. CO2 is denser than either of those, so your reactor will initially release those two gases until the entire space has been replaced by CO2, after which point it will mostly be pure CO2.

CO2 is denser, but its density is negligible since it will immediately start to diffuse and mix with the other gases, and standard gravity is not a strong enough force to overcome the kinetic forces of gaseous molecules. Gases of different densities won't stratify at standard gravity, instead they gradually spread until the space is evenly occupied.

Not that it matters, though (just thought it was worth mentioning). The effect is the same: slow-dissolving N2 and O2 getting "trapped" in the reactor.

OK. I ordered 3 glass drop checkers from Aquatic Magic. They are Chinese knock-offs. they are coming from Malaysia, so they will probably be here next year in January. Thanks for the advise, encouragement, and simply following this thread.

Are you getting any bubbles. I noticed when I increased mine to around 3bps I am starting to see little bubbles coming from the tube. I have been meaning to build a larger Rex style reactor so maybe it is time.

I might have to much flow so not long enough to dissolve it all.
