About Precision Marine Pro Series Refugiums 🇺🇸


Precision Marine Pro Series Refugiums offer an upgrade from our Classic Series. The Pro Series utilize the Precision Marine Quiet-Flow system to bring aquarium water to the reservoir and into the micron bags. This is accomplished by using a baffle to isolate the water, control any turbulence and then direct that gentle flow of water into the micron bags. 

We do not use .177 or .220 Acrylic on any parts like nearly all of the others.

The Precision Marine Pro Series takes filtration to the next level. With the Quiet-Flow System, incoming water from the tank is routed to an isolated chamber to capture and control any turbulence and direct that gentle flow of water into the micron bags for 100% mechanical filtration.

No cost-cutting measures are taken and the build quality is top-notch. 

  • The adjustable water level gimmick: We have never found a respectable skimmer that doesn't perform properly in 8" of water. Nor too high or too low. So, why pay for it? With a Precision Marine sump you're getting better quality, thicker acrylic, finer machining and attention to detail for the same cost.
  • The probe holder gimmick: Users of electrodes or probes should have the ability of placing them where they want. That being said, magnetic probe holders give you the flexibility of locating the holder where you want, and they're cheap! Another "feature" you're paying for.
  • The “Platforms for media” gimmick:  Let's face it, filter media is best used in a media reactor where 100% of the water is exposed to that media, regardless of the type of filter material (Bio-Pellets, GFO, Activated Carbon, Nitrate Removing Media, etc). Most types of filter media only perform as intended when it’s fluidized (moving in the reactor). And besides those points.... who doesn't use a media reactor these days?

Lastly, these are refugiums we’re talking about… why mechanically filter out the very organisms that are being cultivated in live rock and sand (in your refugium)? It doesn’t make sense. The sponge included in our sumps are used as a last resort if your skimmer creates uncontrollable bubbles. The 3D grooves in our dividers (bordering the refugium and bubble trap) will protect the return pump from debris. Why pay for this “feature”?

Being a protein skimmer manufacturer for nearly 20 years, we understand the importance of a large area for a robust skimmer. Take a look at each of the models specifications to be sure your skimmer will fit. Don’t hesitate contacting us for advice on which skimmer to choose.
