Nano Reactor?

[SeanCallan]

What is the smallest possible acrylic tubing that could allow for another "inner" tube for the pumping aspect?

Would it be more desireable to utilize a short&fat reactor vs a tall&skinny?

Just curious as I want to get my nano running

Usually people dont use Ca reactors for a nano. Its easy just to dose manually since its not a heavy load. If it was my choice, I would choose for a short/fat. There is more area for the water to circulate instead of a skinny chamber.

in 1/8" acrylic tube it starts at 1 1/2" OD and increases up to 4" in 1/4" increments. At the point is sometimes jumps 1/2" increments. So the smallast you could do is 1 3/4" OD with an inner chamber that has the 1 1/2" OD. That might be a little small though
