My 1st generation 150 pump power cable started to fall apart, so I decided to replace it before it shocked everything. Generation 2 pumps are impossible to find. So I bought a generation 3 pump only kit.
Then I found out that the new generation 3 pumps are not compatible with the generation 2/1 controllers. The new series pumps are supposed to be sine wave pumps = quiet drive...... So now I have a pair of Generation 3 pumps, and a new controller. will be installing them soon.....more to come on this subject
