Aqua Ultraviolet UV Sterilizers will eradicate algae, bacteria, and protozoa without any harmful chemicals or additives!

UV lamps emit a wavelength that will alter and disrupt the DNA or RNA of single-celled organisms. Combining the UV lamp into a large housing allows for maximum contact time with the lamp allowing the sterilizer to be much more efficient. By changing the flow rates through the body of the UV sterilizer lets you target the specific issue you may be having. Most reefers will report that their tanks water clears up overnight with others taking just a couple days, and as long as the UV is running, the water will stay crystal clear! 

  • Clear Blue Quartz Cap - Lets you see when the lamp is on
  • Outlet Hook - Mounts onto the top edge of most standard aquariums
  • 1/2" Barbed Inlet - Connect any 1/2" tubing for a simple implementation
  • Durable Body - Designed to last longer than traditional UV sterilizers


Great for tanks up to reef tanks up to 75-gallons

Suggested flow rate for saltwater aquarium sterilization - 233 GPH


Advantage Series UV

Quickly implement a UV onto almost any aquarium in minutes! The AquaUV Advantage series includes a hang-on-back style hanger that houses the output flow from the sterilizer, meaning you only need to plumb the input and the rest will be taken care of. They are great for quarantine tanks, nano and pico reefs, or even portable frag tanks for swaps and shows to ensure crystal clear water.


How UV Works?

Ultraviolet sterilizers are used in a wide variety of industries for sterilization, and in your saltwater aquarium they work wonders at controlling unwanted bacteria and protozoa at low flow rates, but at higher flow rates can help maintain free-floating algae which are a common cause of cloudy tank water. The UV Lamp emits a UV-C wavelength that will pretty much destroy the internal structure of any single-celled creature that comes in contact with the light. Aqua Ultraviolet sterilizers include a clear-blue cap that lets you see when the lamp is powered on, without having to risk any exposure to the harmful UV-C rays. By varying the flow rate through the sterilizer and increasing or decreasing the amount of time the water is in the body will change what your UV sterilizer will be targeting and we highly suggest using a gate valve or a DC pump to control the flow through the UV sterilizer. 



Over time the efficiency of the sterilizer will start to diminish because the lamp is no longer putting out the same amount of energy, but also the quartz sleeve that houses the lamp can become coated with mineral deposits and start to become cloudy. By replacing the quartz sleeve about once per year, and also the UV lamp, your UV sterilizer will work just like it did on day one. Most reefers will know it is time to replace the bulb and sleeve when algae starts to grow on the glass, rock, and other surfaces more rapidly.

Product Questions

For a 40 gallon mixed reef, what pump would I use with the15 watt?
Question by: Debra on Jun 15, 2023, 2:25 PM
The suggested flow rate for this is 233 GPH. I would recommend the Sicce Syncra Silent 1.0 Pump.

Which bulb do I use to replace the one I have now?
Question by: Arnie Albrecht on Feb 14, 2023, 6:18 AM
Answer by: William Reed (BRS Staff) on Mar 16, 2023, 10:51 AM
Is there a downside for going too big? I'm planning on using this from time to time for my 10 gal QT and 13.5 gal nano and wondering why not go 15W instead of the 8W.
Question by: Tom L on Jan 30, 2023, 10:26 AM
Thanks for the question! Going too large for a UV sterilizer is going to add extra heat to the aquarium as well as possilby oversterilize

Where do we obtain replacement bulbs and quartz?
Question by: Corey Bender on Jun 30, 2022, 11:33 AM
Hey Corey, thanks for the question. You can find the sleeve by searching this SKU 212493 and the bulb via this SKU 212494
Answer by: James Johnson (BRS Staff) on Jun 30, 2022, 4:21 PM
What pump do you recommend? This will be for a 75 gal.
Question by: Christine Jenkins on Feb 26, 2022, 12:50 AM
Hey Christine, thanks for the question! I would personally recommend a Sicce Syncra Silent 1.0 or 0.5
Answer by: James Johnson (BRS Staff) on Mar 8, 2022, 4:37 PM
Are there any attachments made that can redirect flow other than straight down.
Question by: William Rogers on Feb 2, 2022, 8:25 AM
Unfortunately, there are not attachments for the UV.

Can the quartz sleave be cleaned?
Question by: Glen Scharer on Sep 6, 2020, 9:18 PM
Hey there,
Thank you for reaching out to us! Yes, you can soak it in vinegar or citric acid. It is recommended to wear gloves while doing so.

Please let me know if you need anything further and take care!
Answer by: Matt Lucero on Sep 9, 2020, 10:08 AM
Will this be to big for a 25 gallon AIO nano tank?
And can it hang in the back compartment where the skimmer instead of hanging off the back of the tank?
Question by: Eddie on Mar 9, 2020, 9:25 PM
Hi there,

The 15 watt would be too big, you need the 8 watt. This sterilizer cannot be submerged, it has to hang off the side or back of the tank.

Take care
Answer by: Thomas Billington on Mar 11, 2020, 2:37 PM
Current setup is Red Sea reefer 350 with emerald 26 sump, would this work for that setup?
Question by: Rob Gleason on Mar 9, 2020, 7:07 PM
Hi there,

This sterilizer has a drain spout that is meant to HOB of a tank, with a width of 1 1/8" I do not think you could hang the spout over the rim of the sump. I would recommend a traditional sterilizer with input/output tubing.

Take care
