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: 600 gallon or less

  • Inlet/Outlet: 2" Slip Unions

  • Minimum Operational Flow Rate: 450 GPH

  • Maximum Operational Flow Rate: 600 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

  • Essential piece of equipment By medtoad on 8/29/2016

    Bought this after I saw a spot or two of ich on my tangs in my 320 g reef tank (380 total volume)and knew I would probably would struggle treating such a large volume. By the time I received the unit (and waited for the replacement quartz sleeve that broke in transit initially) one of my fish (powder blue tang) was quite sick. I set it up and run it with an about 400 gph pump (probably significantly less with head pressure and it flows through my chiller too) and within two weeks, my fish looked much better. They still get occasional spots, and when they get more (takes 2-3 months) I know I need to clean the sleeve (gets covered with calcium...easily cleaned off with acid solution and the whole process takes less than 10 minutes) and the fish are fixed again. Unless you think you are perfect at quarantining , I think this is and essential piece of equipment
  • Awesome By Aaron on 12/17/2015

    I hardly ever right a review for anything but, this unit compelled me to do so. So if anyone is on the fence I hope this helps. I just got this unit and it's so far it everything as advertised. Unit is sturdy and looks well made. I piped it in to the manifold and the next day the water was the clearest I've ever seen. I was brought down the wrong road when I started my tank. I was told to get a little submersible unit. Not good never saw any results. So listen to these guys at BRS they know what they are talking about with theses units. It may have a larger price tag but, it was the best larger purchase I've made for my tank.
  • Well built By Daniel on 12/11/2015

    Well built, no leaks easy to assemble,
    Hoping on good results ..
  • Great Product By rldcpa on 6/21/2014

    I've read all the reviews here and remember that for the 80 watt unit to be effective against disease such as velvet or ich, the water throughput should be no more than 240 gallons per hour not 460 gallons.

    Also remember that these units can't cure ich but can remove any disease that flows through the unit. So it can not get rid of parasites in the sand or on fish.

    For me the water clarity has increased so that the water is as clear through the sides as through the front. My algae is non-existent other than a bit on the glass that I clean every few days.

    I have had no deaths or disease in the year since I got the unit and have added a number of fish.

    Remember to clean the quartz sleeve quarterly and to replace the bulb after 1 year. Also replace the gaskets at this time.

    In summary, it was expensive but very worth it for the clear water, no algae and no diseases since I got the unit.
  • Do your research By Michael on 1/8/2014

    This is the brand has been used on many commercial purpose, I did a lot research on what are the best UV out there, Emperor even advertise their output lower than what they are actually producing, don't buy cheap units thats made for profit only. You get what you pay for!!
  • Poor Performance By Joe on 1/3/2014

    I put one of these 80 watt units on a 150 Gallon Tank and verify I was pushing 460 gallons per hour thru the unit. I'll admit I thought I had the world beat sine the unit is rated for a 600 gallon tank. So I got fish and put them straight into the display tank. It turned out they had ICH and this breakout was NO DIFFERENCE then any other time. It was as if the unit was no even in the system.

    Sure I should have put them into the QT but you would think since this tank is 1/4 of what it is rated for it could handle it but like I said I saw no difference.

    The money would have better spent making my QT better.
  • Awesome destructive UV power! By Seth The Wine Guy on 11/28/2013

    I have been using this unit on my tank for 2 years now on a 200g twv system. Prior to this, I was using a 40w Aqua UV and had the tank completely wiped out twice. Once with ich and once with velvet. Four figures in livestock loses.
    In the two years since running the Emperor 80w HO on my system I've not had a loss since. My water clarity is pristine and only need to run the UV during "lights on" periods to achieve success.
    Oversizing the unit for my tank allows me to get twice the bulb life saving money over the longterm. I bought a much larger unit than my tank needed for future upgrades. You can't go too big with a UV on your tank. So, bump up one size from what you think you need and let it rip on your tank and future upgrade!
  • Should have been my 1st purchase after my tank! By Holyreefer on 4/28/2013

    I should have purchased this unit 14 years ago!
    I LOVE IT AND there is a HUGE difference of algae and ive also noticed the ick that would come and go on my Powder blue and my Achillies hasn't soon at all. Very easy to setup instructions are very clear. GREAT PRODUCT
  • Works great By Blake on 1/8/2013

    I installed this sterilizer on my 300 gallon reef system after a algae bloom. In 24 hours the water was clear

Product Questions

How can I be sure my unit is working. I started getting alge in my pond so I replaced the bulb (80 watt h o u v). It has been a little over a week and no reduction in alge yet. Can I pull the bulb out slightly and turn it on or is there a better/safer way. Love my unit and thank you very much in advance for your help.
Question by: Bob quinn on Apr 11, 2016 7:36:00 PM
Great question!
The UV sterilizer housing should have one end with clear plastic on it which will glow sort of Blue when the unit is running. Feel free to let us know if you have any further questions!

If I am putting 2 of these together where the out put of one goes to the input of the other do I double the flow rate to 900/1200 gph since you are doubling the exposure time by going through two in a row? My total system is around 1000 gallons.
Question by: Jon Smith on Apr 3, 2016 2:22:00 PM
Great question!
As you are doubling the contact time by increasing the length of the water coming in contact with the bulbs you can increase the flow to ensure no flow loss is occuring. You do not need to double the flow exactly and .5 to 1x more flow can work well You will want to ensure the flow coming out will remain above the minimum and under 900 GPH. Feel free to let us know if you have any further questions!

I have a 100 gallon tank but plan to upgrade to a 150 or 180 in a couple years. Should I buy the 80w or the 40w. It is possible to go too big on buying a UV sterilizer?
Question by: David on May 2, 2016 6:31:00 AM
Great question!
Realistically the 40 watt regular sterilizer will be a fantastic option for your current and future tank builds. Feel free to let us know if you have any further questions!
