Turns out that Milwaukee's threading is custom. So modifying their regulator might not be possible without it getting way more complicated than Im willing.
As far as what Im trying to accomplish...
The tank is a 45 gallon, so 3' long and 2' tall, but only 1' front to back. Its kind of an odd size. In the past Ive had trouble dialing in the right amount of circulation/flow. Either I have too much or not enough.
Since Ive torn it down and am rebuilding it, I thought I'd take my time and see what I could do to tackle that (and some other) issues. So, what Ive done is purchased two canister filters that individually aren't enough, but together do a great job without creating too
strong of a current that will overwhelm the small fish Im planning on stocking (ember tetras and pygmy cories) or blowing around some of the taller plants.
As I mentioned, Im trying to minimize the amount of equipment that will be inside the tank, so Ive decided to use inline diffusers instead of the traditional variety. I figured if I could do the double injection, then I could get better CO2
distribution. This might seem like overkill, but in my planted 20 long there is a difference in CO2
from one end of the tank to the other and it shows with some of the plants that are in there. I'd like to minimize/eliminate that when I get my 45gal back up and running. Especially since Im hoping to get some good growth out of the DHG and DBT that will be going in there.
