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 Pentair 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

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

SMART UV High Output Manufacturer's Manual


UV sterilizers are most effective as a preventative measure against disease outbreak. While not infallible a properly sized and set up sterilizer will add a significant barrier to disease outbreak. Protecting your system and it's inhabitants will ultimately save money, promote long lived healthy fish and increase satisfaction received from the hobby. Sterilizers can also be used as a component of an effective strategy to current outbreak. Primarily to help ensure the outbreak doesn't re-emerge after treatment. Anyone who has had the misfortune to encounter an outbreak will appreciate the importance of preventive measures against future problems.


Bulk Reef Supply carries only the Pentair Aquatics line of UV Equipment because we feel they are the best UV sterilizers available to the aquarium industry and one of the few brands that offers legitimately sized units capable of fulfilling their claims.


Pentair Aquatics UV Sterilizers are superior to the competition in the following ways:


  • Sterilizers are accurately sized based on contact time, flow rate and tank volume to achieve realistic results.
  • Suggested sizes are based on end of bulb life to ensure continuous results
  • Suggested flow rates factor in the water clarity and UV Transmittance of typical aquariums rather than basing them on purified water.
  • Unique design maximizes the effective contact time by utilizing the full bulb length.
  • Pentair aquatics is trusted by zoos, universities and public aquariums including Duke University, Monterey Bay Aquarium, SeaWorld, Georgia Aquarium, USDA Agricultural Research

  • Outstanding product By Scott on 7/11/2017

    I bought this 50 watt SHO 4 years ago having lost hundreds of dollars of fish to disease breakouts with inferior brands. Since this purchase, my water is crystal clear without carbon use, and no deaths or infection problems for 4 years with this unit. I replace the bulb every year on my 160 gallon and that is all the maintenance. An Emperor UV sterilizer should be at the top of anyone list for their expensive saltwater tank. BRS thanks for recommending the best and not even offering the hundreds of other companies inadequate sterilizers!
  • Easy install and immediately effective By Michael on 3/10/2017

    I installed two of these units on my 335gal nature style freshwater. I installed each directly in line at 300gph per return line in order to protect against parasites/protozoa.

    At the same time I replaced all my flexible hosing. The return lines from the UV units are still clean and clear, while the lines from the trickle filter to the UV units is starting to show some discoloration. So I know the units are having an effect on free floating algae for sure.

    The main benefit for these units for me is I know is the substrate gets disrupted any parasites or pathogens in the water column will be immediately attacked and less likely for any livestock impact. They were easy to install and have been functioning well.
  • Excellent product By Bgp230 on 1/8/2013

    I have this on my 300 gallon reef system and it works great. I had a allege bloom and installed the UV , and overnight it was gone

Product Questions

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 pump would u use for it?
Question by: Jon on Jul 4, 2016 1:10:00 PM
Depending on the height the pump will need to push up to the sterilizer and the overall goal we would suggest looking into the Sicce Syncra 3.0 or 3.5 pumps and then just adding a ball valve to fine tune for lower flow applications through the sterilizer. If you are looking for a high flow application either the Waveline DC6000 or the Ecotech Vectra M1 would be good choices.
