I am interested in investing in new Tunze pumps and lean to get 2 Tunze 6105 pumps with electronic controllers for each of the pumps. When buying these pumps, will it be possible to control the pumps with 1 controller (while both are connected master/slave) or would I need an extra feature to get the 2 connected? I see that there is a second option available in a Turbelle Stream Kit II (TS24) which comes with 1 controller for both pumps. The idea is to replace my existing Vortech MP40's with these 2 pumps in a peninsula style tank with both pumps at the overflow side. Anybody with experience?
