Quick Overview

Emperor Aquatics is now Pentair Aquatic Eco-Systems.

Why does BRS recommend this?

When it comes to UV most other companies will recommend a small UV for a large tank which in reality won’t do much more than make your water look a bit clearer.  If your ultimate goal is to keep bacteria, protozoa, and other free floating pathogens at bay there really is no better choice than Emperor Aquatics for UV sterilizers.  With their real world ratings, we have tried other UV sterilizers and really nothing else has come close.  Even though they are a bit more expensive than other brands, their performance makes them worth every penny.

Suggested Aquarium Size: 480 gallon or less

  • Inlet/Outlet: 2" Slip Unions

  • Minimum Operational Flow Rate: 285 GPH

  • Maximum Operational Flow Rate: 476 GPH

Emperor Aquatics High Output series features a 5" reaction chamber. When used properly UV Sterilizers significantly reduce the chance of encountering disease or algae outbreaks.

What's the difference among UV lite, UV, and High Output UV models in practical terms? For example, in my case, for a 135 gallon reef system in my home? Which of the 40 Watt UV lite, the 40 Watt UV (not lite), and this 50 Watt high output and why?
Question by: David on Nov 25, 2013 4:49:00 AM
Hi David,
The difference between the lite and the standard is the diameter of the reaction chamber. The lite models are thinner, take a bit less space but because of the decreased diameter, have decreased contact time and are thus not as effective at treating as large of tanks. The high output models just happen to use a bulb that has a higher output wattage and is just basically a designation of the bulb/ballast type. For a 135g tank any of the above would suffice, though my preference is for the 40w standard model as you get a significant performance bump for just a few dollars.

What size pond would this unit work for, and, can this unit be used outdoors?
