Used for 2 yrs and did a citric acid wash every 4-6 months.
I love this pump and will hold onto it if need be.

pump is dead quiet at max flow with skimmer and MP40’s off. I really love the RMP feature, as soon as rmp drops from setting, time for a citric acid bath for optical performance.

controller still has plastic over it, I just peeled it to make sure I never removed it.

I had to upgrade my return pump to something slightly bigger.

150.00 shipped to lower 48 states
140.00 PU 83646
