The PS-120 Protein Skimmer has an internal DC powered pump which greatly reduces its footprint. The Base has a diameter of 5 3/4″, 6 1/2″ including the gate valve. The skimmer is 19″ tall with a neck diameter of 2.5″. The Cup diameter is 5.5″ with a height of 4 3/4″. The 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-120 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-120 uses less power the lower you run your pump. At full power, the Nautilus DC-300 consumes 12watts from the wall. At 50% power? 6 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-120 Skimmer works on:

Light Stocked Tanks up to 250g

Medium Stocked Tanks up to 200g

Heavily Stocked Tanks up to 120g

    Crazy Fast Shipping, Logan really cares about the customer. D300 Plus skimmer is a beast! Love the DC setup and adjustability. This thing pulls a dark skimmate right away. Definitely recommend this unit.

    Great skimmer with advanced features like DC motor, slow start-up to prevent overflowing cup and cup fill sensor. A LOT of skimmers look pretty much the same, including high priced ones like Reef Octopus, this one does everything they can do and more.

    Unlike many other skimmer where they recommend you buy 2x your tank size, these skimmers are correctly sized. Never quite understood why companies didn’t just advertise what the skimmer would actually do. My system is 100 gallon total volume which falls directly in line with this skimmers spec. Ive run my skimmer for 60 hours now at about 80% power and it is already doing an excellent job. I had another brand rated for 180 gallons and this one looks to be doing a better job already AND it is dead silent. Didn’t know you could make a skimmer this quiet. Given time I’ll know better how this skimmer will fare but given my past products by coral box and how this is doing now, I’d say I’d put it up against other skimmer that cost 3 to 4 times as much any day.

    Over the last 3+ decades I have owned skimmers from many different manufacturers, I’m simply amazed at just how well the coral-box DC skimmers work and they are incredibly quiet.
