Comments: The Dolphin Amp Master Pumps are excellant main pumps for large systems. i have used them for over 6 years with only 2 seal replacements in that time. The last pump was purchased as a spare pump to allow cleaning and repairs. Great equipment.

Comments: In line micron filters are filters with very fine openings to remove the finest suspended particles in sterile pool water, not biological systems, due to rapid plugging with bio slime. They require pumps able to run at higher pressures such as the Dolphin aqua sea models, not any amp master pump which are designed to silently and efficiently move water at low pressures. Any system that incorporates a micron filter can not be an energy efficient system and therefore can not be operated with the ultra efficient amp master pumps. This person's problem is not the pump, it's his knowledge of filtration. This is a great pump with a plethora of industry uses. It is a rising star in aquaponics! I think I have called this company more than I call my mother asking questions, and they never tire of hearing from me or answering some heavy technical questions.

Comments: I have 2 GE 1 in. High Flow Clear WH System inline filters one with a 10 micron and the other with a 5 micron filters and NOTHING else connected to this pump Dolphin Amp Master Diamond Freshwater/Marine Abrasive Proof 100 Pump - 6250 GPH (Type-4) and it can push more than 30G an hour! It replaced a ¾hp Seahorse now that is a pump the same filters, same plumbing and it was doing 2000GPH with clean filters 1200-1000 as they got dirty. I have a flow meter with its NIST certificate and recently calibrated and recertified. It was off by 0.00238 Litters Per Hour. I do not get how people can rave about it. Yes I reduced the outtake to 1 inch and that should have brought the water flow down to 4000gl and hour but to less than 30GPH? This pump is NOT a 6250 GPH even when measuring at the outtake spitting water to the air (tested in my pool) I am completely disappointed at it. Yes it uses less power than the Seahorse but the Gallon per Watt ratio is way higher!

Comments: I've had a Dolphin Amp Master on my 400 gal tank for two months now and the pump is quite and amazingly cool to the touch. I installed a cooling fan to cool the enclosed compartment below the tank but the Dolphin runs so cool I unplugged the fan.
