Review: Great addition but be prepared to MONITOR the water quality if adding to an established tank! - Worked like a charm! I had a persistent bacterial bloom in a 65 gallon freshwater cichlids tank that no amount of cleaning or frequent 15-30% water changing could remedy. My Fluval 405 filter wasn’t making a difference whether I cleaned it monthly or every 90 days. I asked my LFS their opinion on UV sterilizes and was given a “won’t hurt if you try” response. After a lot of research online I paired the 394 GPH flow from my fluval with what I could ascertain was the right wattage and volume UV sterilizer size and read all the reviews I could find on all brands. Decided on the TT 6X and was very pleased with the unit. Sturdy and easy to set up (although I was dealing with splicing it into the flex hose that Fluval seems to love - nothing a little marine epoxy and spare adapter end couldn’t handle) I had it installed and functioning in about an hour. Ran it for 4 days and VOILA crystal clear water! I did lose one fish a few days later. Although the water was clear I didn’t monitor the water quality as closely as I should have. I tested the water when I found a large green terror belly up and as it tuned out, the nitrite level in my tank had spiked dramatically. Every parameter but that was perfect, but one fish RIP and two others clamped tight told me there was a problem that needed immediate attention. Small water changes for 3 days and a dose of live beneficial bacteria to boost my tank had the nitrite back in check in short order. I also backed down the run time of the filter to 4 hours every night. Water quality still pristine after 2 more weeks. The coralife did exactly what I wanted. Had I been coached to check water quality daily after installation the experience would have been flawless. I highly recommend the Coralife UV sterilizers and will buy it again for other tanks. Review: A must have for serious aquariasts - This thing is amazing and very easy to install. I found the instructions to be ok but once you look at it you should know what needs to be done. This thing zaps everything that goes through it and I haven't had and algae bloom since I've had it on and I have hundreds of plants with grow lamps, so it's pretty impressive!!!! One thing before purchase, just make sure what size you are getting matches your flow rate of filter...just because it says it can handle the size of tank ayou have doesn't mean it matches your flow rate and that's the most important part. ## Features - Removes free floating harmful micro organisms from aquarium water - Features a unique twist flow design increases water’s exposure to ultraviolet light improving the treatment of unwanted micro organisms - For fresh or saltwater applications - Easy setup and installation, includes mounting brackets for hang-on or inline applications - Indicator light lets you know when the sterilizer is operating ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0064JHVOE | | ASIN | B0064JHVOE | | Age Range Description | All Life Stages | | Best Sellers Rank | #132,950 in Pet Supplies ( See Top 100 in Pet Supplies ) #589 in Aquarium Lights | | Brand Name | Coralife | | Color | Black | | Customer Reviews | 4.1 4.1 out of 5 stars (449) | | Date First Available | November 17, 2011 | | Date First Available | November 17, 2011 | | Directions | Provide link to instruction manual | | Included Components | Coralife Aquarium Fish Tank Marine Salt Water Turbo-Twist UV Sterilizer 6X, For up to 250 Gallons | | Is Discontinued By Manufacturer | No | | Item Dimensions LxWxH | 16 x 9.25 x 3.25 inches | | Item Package Dimensions L x W x H | 14.76 x 10.04 x 4.41 inches | | Item Weight | 4.8 Pounds | | Item model number | 100115601 | | Item model number | 100115601 | | Manufacturer | Central Garden & Pet | | Manufacturer | Central Garden & Pet | | Manufacturer recommended age | 1 month and up | | Material | Plastic | | Model Name | Turbo-Twist UV Sterilizer | | Number of Items | 1 | | Product Dimensions | 16 x 9.25 x 3.25 inches; 4.8 Pounds | | Size | 6X, 18 Watt, Up to 250 Gallons | | Style | UV Sterilizer | | Target Audience Keyword | fish | | Warranty Description | 12 month limited warranty | ## Images ![Coralife Aquarium Fish Tank Marine Salt Water Turbo-Twist UV Sterilizer 6X, For up to 250 Gallons - Image 1](https://m.media-amazon.com/images/I/61kjz8d1vxL.jpg) ![Coralife Aquarium Fish Tank Marine Salt Water Turbo-Twist UV Sterilizer 6X, For up to 250 Gallons - Image 2](https://m.media-amazon.com/images/I/71ykrgstJCS.jpg) ![Coralife Aquarium Fish Tank Marine Salt Water Turbo-Twist UV Sterilizer 6X, For up to 250 Gallons - Image 3](https://m.media-amazon.com/images/I/71P6sgwnU6L.jpg) ![Coralife Aquarium Fish Tank Marine Salt Water Turbo-Twist UV Sterilizer 6X, For up to 250 Gallons - Image 4](https://m.media-amazon.com/images/I/71mJYiV2gZL.jpg) ![Coralife Aquarium Fish Tank Marine Salt Water Turbo-Twist UV Sterilizer 6X, For up to 250 Gallons - Image 5](https://m.media-amazon.com/images/I/61A8dqX4K9L.jpg) ## Questions & Answers **Q: If i need it to run at 110 gph to kill something, and this sterilizer says u need a pump that does 200-300gph, how can i make it work?** A: On a 6X to kill algae that gives you cloudy and green water 240 GPH is required if you also want to kill parasites out of the water that can harm your fish, then you need 110 GPH (look at chart on last page of manual). So if you have 240 GPH it will kill the algae only but if you lower the GPH it will kill both the algae and parasites because the water flow is slower and is in contact with the UV light longer. I had the same problem so I called the tech people of my pump. They told me to put a plastic ball valve in the tubing coming from the return side of the pump (side that the water is going out of the pump to the aquarium) and turn it down to less than half the flow. (Two Little Fishies ATL5450W Ball Valve for Regulating Water Flow, 5/8-Inch) But by doing that you cut the filtering to you tank to much so what I did was to purchase a separate 160 MPH canister pump (Marineland C-Series Multi-Stage Canister Filter 160 GPH) and put the 6X on that and by the time the pump pushes through the 6X the water flow is slowed to about 110 GPH that is needed. Has been working perfect for a year now **Q: Would this work for ich issue and other infections?** A: 12x helped me to get rid of Ich in my 75 Galon tank, going ich-free for 2 years since I had an outbreak and bought it. **Q: I have a 29 gal tank with a Nano30 canister filter. Can i use this inline? I am looking for something to control algae blooms/green water.** A: Actually if the flow is to fast it won't work. You can call the company or check with a local store to see wat size pump you need. **Q: What would be a good inline UV stabilizer for a 65 gallon tank?** A: I have used a Coralife 18Watt unit on our 55 and 56 gallon aquariums, not much of a stretch for that power for a 65 gallon tank. It has been very successful in those applications, both of the units have been driven by API/Rena XP filters and have successfully maintained great control over algae and bacterial loads. Easy plumbing them into those systems return lines. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great addition but be prepared to MONITOR the water quality if adding to an established tank! *by P***J on March 4, 2018* Worked like a charm!

I found the instructions to be ok but once you look at it you should know what needs to be done. This thing zaps everything that goes through it and I haven't had and algae bloom since I've had it on and I have hundreds of plants with grow lamps, so it's pretty impressive!!!! One thing before purchase, just make sure what size you are getting matches your flow rate of filter...just because it says it can handle the size of tank ayou have doesn't mean it matches your flow rate and that's the most important part. ### ⭐⭐⭐⭐ Works Well -- Happy So Far! *by D***N on May 29, 2022* This is my first time trying one of these out. I did some homework first, just to convince myself that the whole concept isn't bunk. I think the answer to that is just a matter setting your expectations. This is not designed to kill all living material that passes through. But rather, it's intended to "sterilize" in the sense that it damages the DNA of passing microbes sufficient to impede their reproductive cycle. I'll note two issues that I have with the user manual: 1) There is mention of a gasket between the end-cap and the chamber that contains the UV bulb. But there is no such gasket. (At least, not in the unit I received.) 2) The diagram illustrates the plastic bulb stand-off frame fitting at the base of the bulk at the end-cap. But it doesn't go there. It goes at the end of the bulb to prevent it from making contact with the inner sides of glass chamber. As I studied the missing end-cap gasket a bit, I came to the conclusion that they only time that the UV bulb chamber will contain any water is when the inner glass breaks. I suspect that the mention of that gasket is just an error on the part of the manual illustrators. If the glass does break, then that gasket will prevent water from seeping through the end cap. To be on the safe side, I found a 65mm "Osterizer" brand gasket which is a perfect fit. (https://www.amazon.com/dp/B08RDG6KY3) I applied some silicon grease and now I have zero anxiety about the missing gasket, which I still believe is a bit overkill. One thing the user manual does right is that it is very careful to indicate the proper way to route the plumbing. It should be located on the filter outlet, and any shut-off valve should be located between the UV and the filter. I don't think the manual made mention of an explanation as to why this is important. But I believe the reason is because you need to make certain that you never let the UV run dry while it is active. When it is active it is hot. If it runs dry while it's hot, that is when the chamber glass breaks. In my install, I've got a check-valve in the sump which prevents backflow on a power outage. Preventing that backflow will also prevent the UV sterilizer from suddenly running dry in the same event. (I suspect this might be what is behind claims about the glass breaking.) For my install, I also had to think long and hard on how to mount it so that I can change the bulb without having to undo any of the plumbing connections. As for the affect on water quality, I am very pleased! It has turned out to work as well as I hoped. I began to notice an improvement in the first 48 hours of run time. ## Frequently Bought Together - Coralife Aquarium Fish Tank Marine Salt Water Turbo-Twist UV Sterilizer 6X, For up to 250 Gallons - VIVOSUN 210GPH Submersible Pump(800L/H, 8W), Ultra Quiet Water Pump with 3.3ft High Lift, Fountain Pump with 5ft Power Cord, 2 Nozzles for Fish Tank, Pond, Aquarium, Statuary, Hydroponics Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/6640656-coralife-aquarium-fish-tank-marine-salt-water-turbo-twist-uv](https://www.desertcart.vn/products/6640656-coralife-aquarium-fish-tank-marine-salt-water-turbo-twist-uv) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-15*
