- Smart UV 25 Watt - Pentair Aquatics
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.

Excellent UV By LearningDaily on 3/19/2020LearningDaily would recommend this product to a friendI bought this used a 40-watt version of this UV and have had this running on my 90 gallon Reef Tank for several years. I have never changed the bulb but likely now need to as I've seen small signs of algae growth recently. I feed it through a small pump directly from the display and return to the other side. Prior to hooking it up, I regularly lost fish due to diseases from the LFS. I haven't lost one since for this reason. Yes, it is significantly over-sized for my tank and that is why the extended bulb life wasn't an issue. I highly recommend this unit, sufficiently over-sized for your needs, being fed with a low flow sufficient for both bacterial and algae killing. Pentair provides a manual that identifies the recommended flow rates for the above conditions. Further over-sizing extends the useful life of the bulb to several years.
Quality Unit By Chris on 4/8/2019Chris would recommend this product to a friendThis is my first UV system. I have this unit on a 70 gal tank, 85 gallon total system volume. I kept it turned off for 30 days as I seeded and started my tank cycle, then turned it on 24x7. I regulate the flow off my return pump and monitor it using an Apex Flow Meter. I run mine at about 110 gal per hour. All during the cycle I had absolutely no algae issues and the glass stayed perfectly clean. I am in month 7 now with fish and corals in the DT and started noticing the glass was getting dirty weekly as well as some algae issues on my pumps and equipment - I had not cleaned the UV yet! I took it apart and noticed quite a bit of calcification on the quartz sleeve, I mean it was 90 percent blocked. After cleaning the sleeve its performing great again! Note to self, add cleaning the UV to my cleaning chores! I added an event to my Fusion to clean every 2 months. Its easy.
Cheap Ballast By Jennifer on 10/22/2017Jennifer wouldn't recommend this product to a friendHad to replace ballast 2x in as many years. Called tech support and both times they told me bulb was bad. Bought bulb each time and it was ballast!!! Spent more on parts than I paid for it!!! I would give this a no star if I could, Do Not Buy!!!
"C" is an idiot! By FC on 10/10/2017FC would recommend this product to a friendPentair Aquatics makes the best UV sterilizers in the market and this is why BRS does not offer other brands. Regarding C's comments: When you make a mistake just leave with it and don't blame others. Those UV sterilizers are built like tanks, this is why finding main part components is not easy. I guess BRS and Pentair Aquatics are not used to deal with morons like you this is why you are not getting anywhere.
Superior product By Scott on 7/11/2017Scott would recommend this product to a friendWhen you have hundreds of dollars invested in your tank, a UV sterilizer is definitely at the top of the list. I have tried the cheaper brands and their durability, quality, and stability is not there. I bought a 50 watt SHO from BRS around 4 years ago for my 160 gallon. With no carbon use, the water looks like fish swimming in the air. No problems with infection or deaths. With previous products, that was not the case. I replace the bulb yearly and that is it.
Best in Class By jellyteam on 9/15/2015jellyteam would recommend this product to a friendWhen you get a UV sterilizer it needs to be made out of UV resistant plastic. This unit is. It also has a large viewing window that lets you see your bulb and water flow. I have other units by emperor on several commercial units, they never fail.
I think it works but way over priced for what it does By Kristen on 12/23/2014Kristen wouldn't recommend this product to a friendBought this UV to suppress ick in my tank. Although it was made out of high quality "plastics", I still can't find any reasons as why it cost so much. This UV don't have the feature of adjusting water flow or warns you if the UV bulb needs to be replaced, so there's nothing "SMART" about it. Why they even call it a smart UV?
well built, very good support! By D on 4/16/2014D would recommend this product to a friendI wish that i could comment or reference "C" in this comment but is seems, that person is just for lack of better terms "special" in more ways than one. I am a tinkerer and i took the whole thing apart when i got it. if it un-scewed or came off i did it. thus i fried mine as well. i called customer service and had a very polite gal on the line, who got my plastic and bulb in the mail to me and i received it very fast for where i live..... the story ends with this, some people such as "c" are just people that wont take responsibility for their actions and are just pissed of at the world that their lives suck and that they have no education or manners to make the change.
Well built, very poor support. By C on 1/16/2014C wouldn't recommend this product to a friendJust my 2 cents and heads up to anyone who plans to invest in this pricey UV. I guess I did not seal the unit perfectly and after three weeks a small leak caused the bulb contact to short out. Did not realize it until it just didn't light up anymore... Slightly melted plastic at the bulb contact point and gummed up o ring's. I understand, my stupidity I guess. Not EA's fault. I should have checked and double checked the seals better before putting into use. So due to the slight damage, I need to replace the plastic parts where the quartz sleeve is held, new o-rings, etc. power supply connector and of course a new bulb. Should be a easy fix I thought. Contacted EA and was referred to buy the parts from BRS. BRS, only carries some of the parts and EA was not helpful at all to help in getting me the other replacement parts. I think after attempting to get the few parts I need, I mine as well buy another new unit. Would be less trouble and probably the costs would not be far apart. Expensive little mistake... Be careful using this near water. As separate parts seem to be not easily accessible. I assumed something of this caliber would have a great backing from the company. One of the very few experiences in my life I thought I was buying the best of the best and after three weeks, it is going in the garbage can. I had junk fish gear that lasted me longer than this and easier to get fixed. Just my experience with support. UV probably works great if it worked for me.
Best By Gasman on 9/16/2013Gasman would recommend this product to a friendIf you are going to buy a UV sterilizer,Emperor is the one to get.Consider it an insurance policy against Algae and disease out breaks.It won't prevent either,but it will decrease their severity from catastrophe to something you can manage.You will also enjoy clearer water.
solid By Pius W on 8/29/2010Pius W would recommend this product to a friendI have been using UV on my reef tanks for over 20 years now and tried virtually every brand of UV sterilizer there is. Emperor aquatics is by far and away the best one out there. I would give it 6 stars if i could. This thing looks and feels like it belongs at seaworld rather than my home.
I plan on using this in my main display tank, even though I will quarantine all fish & dip all corals, so what rate flow would you recommend for preventing any sort of diseases or outbreaks in my main display tank for prevention?
Do you guys have any research on what, if any, impact the use of UV has on ORP? I am seeing some suggestions that it can potentially boost ORP and am a bit curious if it would be worthwhile to have my ORP sensor control when to run the UV.
Unfortunately we have not looked into UV's effect on ORP. We still us ORP in conjunction to keep consistent levels when dealing with Ozone however UV should not have the same impact as Ozone on ORP levels. Feel free to let us know if you have any further questions!
Do you stick or recommend where I can get the right pipe clamp support to mount this model?
We do not have the mounting option for the UV sterilizer for sale however it may be available through the manufacturer directly. Feel free to let us know if you have any further questions!
What size pcv pipe holder will I need to secure this sterilizer?
You will need the 3" PVC pipe clamp. This will be a slightly loose fit however will hold the Sterilizer perfectly! Feel free to let us know if you have any further questions!
I am VERY interested in buying this UV unit. In doing my research first, I was wondering how often are you having to replace the bulb( not to the day, just a ballpark)?
For best performance you will want to replace the bulb once every 1-2 years to keep up with the proper amount. Feel free to let us know if you have any further questions!
Will this kit provide me with everything I will need or do I need to get a pump, tubing, etc...? I am Fairly new at the hobby and hadn't used a UV sterilizer before.
This will not come with any of the plumbing supplies. However this can be plumbed in to make it barb fitting which can work with 1/2" tubing. This is a common size for most pump and would work well!
1⁄2” Schedule 80 Straight Barb x Male Thread
Reducing Bushing 1 1/2” Spigot x 1/2” Female Thread
What size hose barb fitting would I need to order with this UV sterilizer?
I would plumb the UV sterlizer with tubing no smaller than 3/4" tubing to avoid excessive back pressure on your pump and the resulting flow loss.
I hope this helps!
What is the difference between the Smart UV 25 watt and the 25 watt lite. I see that the lite is rated for a 90g while the other is 130g. Why?
The difference will lay on the size of the water to flow through the reactors. The Lite is a smaller design with less contact time for the water. Feel free to let us know if you have any further questions!
Of the 2 water flow rates(algae+bacteria or protozoa), which would be the more appropriate for controlling dinoflagellates?
The best flow option would be the Bacteria, Algae flow as this will not help to sterilize established algae or Dino but rather will keep free floating forms in the water column from reproducing. Feel free to let us know if you have any further questions!
Did you mean to say that the UV Sterilizer has a body diameter of 3 inches?
Sorry I don't quite follow your question but this unit does have a body with a diameter of about 3.5"
