Co2: This Aquarium

Though I stress to folks new with aquatic plants, for a Co2 system, to purchase a disposable can of Co2($10) and to fill up a submerged plastic bottle with Co2. Because I have so many tanks I use a hybrid type system. Instead of a steady stream of micro-bubbles I click the regulator on and fill the reservoir, where it is absorbed into the water all the same.

Perfect timing, I just started looking into co2 for my 90g, and this popped up on my for you page. Great video, very informative. Thanks a lot!

Not quite sure i get the idea or how the co2 was being filled. Can you probably show the process up close? I saw you turned the valve on and then turned it off, but didn’t quite get how the bottle is filled. Is there an inline tubing connected to it?
