then I found this info.....
The AC 30 case is 6" across and the basket area is 4".
The AC 20 is 5" across and the basket area is 3".
They are both 6" high.
They have the same motors and impellers.
The carbon media bag is the same.
There is slightly less biological media for the AC 20.
The AC 30 has an extra intake pipe.
hope it helps you identify what you have.
This info is incorrect. All Aquaclear filters use only one inlet tube. While the motors are the same, the impellers for the AC20 and AC30 are different sizes (I have one of each as I modified an AC70 to use the impeller from either the AC20 or AC30 [reduced flow for bio-filtration]).
I believe that the filter pictured to the left of the AC110 is an AC20.
