Hi Roger, I have a large reef 600 gallons (400 gallon display and 200 gallon sump). I am looking for an alternative to my reeflo manta ray. It just pours heat into the aquarium and runs on alot of juice. I am dealing with about 25 feet of head and i am also teeing off some of the flow to my UV sterilizer,refugium and chiller. Does tunze make anything that can handle this load. Everything on the tank is tunze and I have yet to have any problems. I have tried lower voltage pumps such as the reeflo hammerhead and it cannot handle the head. I noticed Tunze makes recirculation pumps. Thanks in advance.
Tony
