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 you really can't do much better 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.


Bulk Reef Supply carries the Pentair Aquatics line of UV Equipment because we feel they product some of the best UV sterilizers available to the aquarium industry and are one of the few brands that offer legitimately sized units capable of fulfilling their claims. Pentair Aquatics SMART High Output UV series features a compact space saving design which utilizes a 5" reaction chamber. When used properly UV Sterilizers significantly reduce the chance of encountering disease or algae outbreaks.


Pentair Aquatics UV Sterilizers are superior 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


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.

Product Questions

I am modifying my plumbing. I may need to replace the union collars. Will any standard 2-inch union collar work? Thanks.
Question by: gary newman on May 3, 2020, 1:13 AM
Hi Gary,

Unfortunately you will need to source new union collars from Pentaire as we do not have any that will match the threads. Alternatively you could try to cut your existing plumbing so that you have enough pipe left to add a pipe coupler.

I hope this helps!
Happy Reefing

Can the unit be operated if the quartz sleeve is cracked or broken?
Question by: John Hildebrant on Mar 11, 2018, 6:34 PM
The quartz sleeve must be replaced if cracked or broken to avoid electric shock.

I'm considering the 80W or 50W units. The 80 almost doubles the UV-C output. My reef tank will be 330 plus 65 in the sump. I have a fish room and will run off the return. I don't want to add extra heat unnecessarily either from the bigger unit but don't want to straddle the line on size of unit. Price difference is minor between them. Thoughts? Thanks!
Question by: Jim Whelan on Jan 17, 2018, 12:21 PM
In our opinion, if you are going to go with a UV system, go big or the benefits are going to be very negligible. The heat transfer is something to consider but with decent heat management, it shouldn't be the deciding factor. You could always set the light on a timer or controller to turn off when the tank gets warm.

What is the estimate for how long a bulb will last?
Question by: Brian Buschmann on Dec 8, 2017, 11:16 AM
Hi there,
Thank you for reaching out with your question.
Pentair states that the bulb should be replaced after 13 months (9000 Hours) of continuous use.
Please let us know if you have any other 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 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!
Answer by: Connor on May 3, 2016, 6:58 PM
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 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!
Answer by: Connor on Apr 14, 2016, 4:17 PM
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 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!
