The PS-400 Protein Skimmer has an internal DC powered pump which greatly reduces its footprint. The Base has a diameter of 9″ and a 9.25″ x 12″ footprint including the gate valve. The skimmer is 24″ tall with a neck diameter of 4.75″. The Cup diameter is 9″ with a height of 6.25″.┬áThe skimmer cup has a drain that includes a drain hose and valve.


Every Power Skim protein skimmer includes a fully controllable Nautilus DC skimmer pump. The pump includes a controller with 10 output modes, which allows you to adjust the flow rate from 10% to 100%. There are 3 feed timers, 10 minutes, 30 minutes, or 50 minutes with 1, 2, or 3 presses of the feed button respectively. Press the button a fourth time to end the feed timer and power the skimmer back up.

The Nautilus DC pump also has a built in slow start feature, meaning it starts at 0% and slowly builds up in power until it reaches your flow setting. Every pump includes a float switch, which can be mounted directly into your skimmer’s collection cup. When the cup is full, it will shut your pump off and sound an alarm. The days of bubble filled sumps are over!


The Power Skim PS-400 is powered by our Nautilus sine-wave DC controller. Sine wave controllers use a specific electrical frequency to reduce noise while the pump is running. All you hear is the gentle intake of air and the resulting turbulence from the needle-wheel impeller.


The PS-400 uses less power the lower you run your pump. At full power, the Nautilus DC-1,100 consumes 50watts from the wall. At 50% power? 25 watts. They’re not only efficient in terms of power use. The Nautilus DC pump allows you to dial in your skimmer on a level unmatched by AC pumps. That means you can dial in your skimmer to match your tanks specific needs.

The Power Skim PS-400 Skimmer works on:

Light Stocked Tanks up to 600g

Medium Stocked Tanks up to 500g

Heavily Stocked Tanks up to 400g

We provide a 24 month USA warranty on all Power Skim DC Skimmers.

    The Coral Box Cloud 9 Protein Skimmer is a beast. Right out of the box it started skimming and it is dead silent. If you are looking for a skimmer that looks as good as any out there and performs as good if not better then choose Coral Box.
