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 UV series features a compact space saving design which utilizes a 3" 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.

Hi, I am considering getting one of the 40w UVs for my Cade 1800 (~220g total water volume) for dinos. I have a Sicce 1.0 (251gph) pump that I was thinking of using - would this be feasible? If so, what plumbing/fittings would I need to get to plumb using flexible tubing?
Thanks!
Thanks!
Question by: Gregg on May 16, 2022, 10:36 AM
Thank you for your question. I believe a DC controllable pump with a gate valve would be more efficient for use with a UV sterilizer to adjust flow according to changing needs of the aquarium over time. The standard AC pumps with a singular flow rate can be dialed back but also use more electricity when using a gate valve to slow them down. The Sicce 1.0 is on the lower end of the acceptable flow range for this UV unit and with head loss and chamber size on the UV unit, it may not be able to perform as expected. You may want to check out a VarioS-2 pump or a little larger depending on what you would like to control in the aquarium. The VarioS-2 comes with a 1" slip pvc union, while the UV comes with a 1.5" pvc union. For the tubing SKU:210943, clamps sku:203072, reducer on the UV sku: 209997 (qty 2), barbs sku: 209983 (qty2), for that Varios pump(or any pump with 1" pvc connection to barb fitting sku:207927. You will need to determine how much tubing you will require to operate it depending on the installation location, but that should get you started.

Hello, does your 1.5" union ( SKU 202522) fit the threaded flange on the pentair aquatics smart uv 40 watt (SKU 204905)? I plumbed a 1/2" reducer into the inlet/outlet, attached a sicce 1.5 and noticed the max flow is 80 GPH per my neptune 1/2" flow sensor. I need to re-plumb to 3/4" to see if I can increase to the recommended flow. Sorry if this is a duplicate question. I submitted a question last night, but don't remember adding my email address, so that is why I'm posting the question again. Thank you.
Question by: Rick on Apr 17, 2020, 11:39 AM

Can the output be sized down to a 1/2” so I could use the apex 1/2” flow sensor?
Question by: Alan Crawford on Mar 9, 2020, 4:36 PM
Hey there,
It can be reduced but not recommended. That would drastically effect the flow rate by reducing more than 50%, putting a ton of back pressure on your pump.

Does BRS sell the bracket (clamp) to secure the UV sterilizer ?
Question by: RobertCA on Sep 13, 2017, 12:25 PM
We do carry surface mounting clamps that can be used with the Pentair UV sterilizers. The 40w version does have a 3” body and the 3” mounting clamps will work with that sterilizer.

Answer by: Tyler Schafer on Jul 20, 2017, 10:36 AM
I have the unit mounted horizontally with the input and outlet positioned downward. But the chamber only fills 1/4 of the way with water. Is this correct, or should it be filled all the way. Or do I have it positioned incorrectly? Not enough room to position vertically
Question by: Don McLaurin on May 15, 2017, 5:39 AM
Hey there,
You will always want to position or plumb the outlet so that the water will fill the reaction chamber completely. The outlet should be at the highest point possible. If you are unable to point the outlet up, you should plumb the outlet so that is goes above the UV reactor in order to prevent the chamber from emptying.
Regards

do this unit comes with any type of holders at all and can i change my inlet/outlet to 1/2 inch, thanks
Question by: Carlos G Rodriguez on Jan 25, 2017, 11:07 AM
Awesome questions! Although there are no hanging or mounting options for the sterilizer itself, you can use these PVC clips to hold it by the plumbing. https://www.bulkreefsupply.com/sm-clamp-for-pvc-pipe.html
You can definitely reduce those fittings to meet your needs! :-)

I've read that UV sterilizers can kill copepods and other beneficial critters, is that true? And if so can I run a UV sterilizer at a higher flow to keep algea at bay but not kill the good guys?
Question by: Eric Boyko on Jan 18, 2017, 8:34 AM
Great question! Most beneficial creatures like amphipods, copepods, and beneficial bacteria do not live in the water column itself. They live in the pores and crevices of the rock and sand and the vast majority of them will not flow through the system and end up in the UV sterilizer. It is possible for a few to make it through, but it will not completely wipe out the entire populations. :-)
Answer by: Randy on Jan 19, 2017, 2:28 PM
Does this setup come with every thing I need for a complete installation or do I need to purchase other items as well such as an additional pump and plumbing?
Question by: Ryan on Nov 23, 2016, 8:13 PM
Great quesiton! You will need to purchase a feed pump with a flow rating around 160 GPH/300 GPH, as well as the plumbing needed to connect to this product's inlet and outlet. The inlet and outlet plumbing sizes are 1½" Union. :-)
Answer by: Randy on Nov 25, 2016, 8:51 AM
Which sicce model do you reccomend for the smart uv 40 watt? Thanks!
Question by: Ryan on Jun 28, 2016, 9:37 PM
Great question!
The sicce 1.0 will work well with no head height. From there if there is back pressure or head height restricting the pump we recommend the sicce 1.5

Answer by: Connor on Jul 1, 2016, 9:51 AM
I thought you need to plumb the UV so that ALL water returning to tank from sump should flow through the Unit. But all of the set ups I have seen on You Tube show the UV being fed from separate pump in sump with water flowing through the UV and back to the sump? Doesn't sump-to-sump set up significantly decrease the effectiveness of the UV?
Thanks,
Thanks,
Question by: Mike on Jun 4, 2016, 1:35 PM
Great question!
With these UV sterilizers in particular they will run on slower flow rates and increased water contact time. In most cases you will not need to return the water up to the tank but simply by drawing the water from an earlier section in the sump to a later section of the sump will improve performance. While ideally a full UV sterilizer could work the current set up with a feed pump works great on al of our units! Feel free to let us know if you have any further questions!

Hey there,
I'm curious to know if 40 watts is too much for 150 gallon reef tank? Can you have too much wattage to gallons? I just want to make sure anything that passes through it gets nuked. Let me know what you think.

Can this be installed using an existing manifold?
Question by: Alex N on Mar 28, 2016, 9:20 AM
Great question!
This certainly can be used with existing manifolds very easily. The unit will come with appropriate barb fittings to connect to 3/4" soft tubing. additionally you can use hard plumbing to connect the sterilizer. Feel free to let us know if you have any further questions!
