Quick Overview

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: 90 gallon or less

  • Inlet/Outlet: 1.5" Slip Unions

  • Minimum Operational Flow Rate: 55 GPH

  • Maximum Operational Flow Rate: 92 GPH

Emperor Aquatics SMART UV Lite series features a compact space saving design which utilizes a 2" reaction chamber. When used properly UV Sterilizers significantly reduce the chance of encountering disease or algae outbreaks.

what pump is recommended for this sterilizer? I have a 75 gallon tank with sump.
Question by: kurt on Dec 26, 2013 6:27:00 PM
Hey Kurt,
Are you trying to target parasites/protozoa (like ich) or what is it that you are trying to target? Different critters require different contact times which are controlled via different flow rates. For these types of organisms for example emperor aquatics recommends a flow rate of 55gph.

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 Emperor 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.


Emperor 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.
  • Emperor aquatics is trusted by zoos, universities and public aquariums including Duke University, Monterey Bay Aquarium, SeaWorld, Georgia Aquarium, USDA Agricultural Research

  • Great! By Dan Thomilson on 3/13/2013

    Great product! I wish ACRA didn't post 3 poor reviews, because this is better than the rating he gave it, just follow instructions and you'll be fine. This unit is so much better than any UV I've tried in the past, I don't know if it's really strong, or the others were way underpowered, but it's fantastic! I've never been so happy with a purchase, high quality, great customer service (had a few questions before the purchase), and overall one of the best additions to my tank!
  • Just A Warrning! By acra1 on 4/21/2012

    U/V sterilizers a must I think,with SPS. Just a note: for those purchasing E.A. for first time,when they say check for water leaks before plugging to outlet. It's not just your plumbing there talking about,the unit comes partially assembled,make sure you take it apart and check compression fitting on quarts sleeve. No warranty on water damaged bulbs,I found out the hard way.

    To first time buyers of E.A. ,unit comes pre assembled except for bulb . make sure you disassemble and check compression fitting on quarts sleeve.
  • Great UV By John on 3/2/2012

    Having used the aqua UV 25w in the past on tanks this one seems to be a more efficient UV and more user friendly with much more contact time.
  • a+ By Erik on 8/29/2010

    I have read a ton of stuff about UV not being worth while. Everyone has a right to there opinion but when added this to my system I found I went from cleaning my glass twice a week to twice a month. I also have never encountered any disease in the tank and I do not quarantine. I think much of the bad rap UV gets is based on the tiny hobby models. This thing is huge.
