Thanks for the reply Craig, if I am reading right, the 6055 is the smallest controllable pump Tunze makes, correct? If I understand your post I can set the jumpers to control speed but can I set the speed and then also control it with the apex so it has a max setting on it? My plan is to put it on the false wall with the magnet in the back chamber.
Also, is there much difference in the standard and wide version?
Thanks.
