Quick Overview

Pentair 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: 60 gallon or less

  • Inlet/Outlet: 1.5" Slip Unions

  • Minimum Operational Flow Rate: 37 GPH

  • Maximum Operational Flow Rate: 60 GPH

Pentair 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.

Product Questions

I want to install one of these in my tank on a separate loop so I can avoid killing my pods. Can you post all the required fittings and pump that would be needed to run this UV filter effectively? Also is there any clips that would allow my to hang this horizontally on my sump. I was thinking maybe like shower curtain clips but is there something specific for this?

Great question! These UV sterilizers will come with 1.5" unions as well as reducer and barb to attach to 3/4" soft tubing. The only items you will need will be 3/4" soft tubing to attach the feed pump and allow the water to return. I have included a link below to a PVC holder which may be able to mount and hold the sterilizer for you!

SMART UV LITE 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

  • Need more time By tbone on 12/18/2015

    Only had it running for about two weeks, I read that this might help with a small cyano problem that Ive been dealing with, well no luck yet, but i will say this thing is built like a tank, its 24" long but the box it came in was 48" long, easy to use, just glued some barbed fittings, waited for the black friday sale!!
  • Worth the extra money By Chuck on 6/14/2011

    These UV Sterilizers are top of the line. These are not inexpensive but you really do get your moneys worth, in fact even more since the way they rate the capacity of the units is really a worst case scenario. They are rated at a "suggested" flow rate which is based on the bulb being at the end of it's 9000 hour useful life span, and also rated based on "green water" clarity, which is nowhere near what you would find in any well filtered system. When you factor in a new bulb and clear water the maximum flow rate doubles and so would the size of aquarium it is suggested to handle. I actually bought the 40 watt model that is rated for a 260 gallon tank thinking based on my past experience with UV sterilizers that you need to go bigger, but it is overkill for my 120 gal. If I had it to do over I would get the 18 watt and I'm confident it would handle my tank fine.

    This is the third UV Sterilizer I have purchased for my tank and I'm sure it will be the last, because it is built like a tank. Unlike the other two which were cheap "Made in China" crap Emperor Aquatics is made in America and you can tell the difference. If you are considering a UV Sterilizer do yourself a favor and go to emperor aquatics website and read through their technical data. Once you get a better understanding of the contact times, flow rates, and UV spectrums required for effective UV sterilization you'll realize that the common cheap hobby UV sterilizers are all but useless and a complete waste of money.

    Without a doubt these are far more expensive than the average hobby units, but I really think that if your budget is tight and you can't afford or justify spending the higher price, that you keep saving until it makes sense. In the end you'll be glad you did.
