I have 2 tunze 6055 turbelle nano stream power heads that can do 250 to 1450 gph. I dont have the original controllers for the but I will throw in a tunze 7092 wave pulse controller to run them and that what I used on them. You can run them without a controller. I am selling the pair and controller for $225 shipped and paypal fees included pumps are having a vinegar bath and will be ready for shipping. Thanks everyone and happy reefing
