I have a 500 gallon Display, 750 gallon total system ( filtration Room under tank in Basement ) seeing my head pressure is about 25 ft I needed something to push that water up to my display Tank while trying to maintain GPH outflow as much as possible so I always ran the reef flow Hammerhead pumps and really loved them as I never had a problem with them. having my 500 gallon tank set up now for almost 6 yrs I have gone through 4 reef Flo pumps I had one rebuilt and kept one running on my system, one day I came across a post here on R2R on a brand new Abyzz A400 ipu pump and purchased it for quite a awesome price!

! well once I received it and hooked it up........ WOW What a game changer!!!!!!! I would have paid full price for this pump now that I can see what it does. hell I can't even run it past 70% because of the power and that is with the pump pushing that water 25 ft high to my upstairs 500 Gallon Display. I love this pump not to mention the 10 yr warranty and OMG!!!! I can't even hear it and it does not even get hot.... my reflow pumps use to get very very hot to the touch. not to mention the power consumption I am saving yeah love that 300 watts at me running the pump at 68%. I have my newly rebuilt reflow pump hooked to my system as a back but I have a feeling ill never need it. LOVE Abyzz pumps! Just my two cents.
