Comments: I have gone through two of these within the last year. The "stainless" steel tends to rust through which technical support claims is as harmless as using GFO in your system. I don't know about you but I don't like my equipment rusting and flowing into my tank. Supposedly China is working on taking out the metal sleeve and redesigning it. I'll give it another look when they do. The plastic mounting clips on my last two also broke over time.

Comments: The internal twist design doesn't increase dwell time; that would be impossible. But it does discourage laminar flow in the unit, so the chances of any pathogens spending some time close enough to the lamp for sterilization are greatly increased. I like the unit. The ballast is suspect (at least from the units of a few years ago). Mine recently failed, so I re-wired with a Workhorse 3, and the intensity of the UV light coming from the indicator window is now MUCH brighter. If you have any DIY skills, I would advise switching to a Workhorse ballast (after the warranty expires).

Comments: This product is almost perfect out of the box. I did quite a bit of research on UV sterilizers and choose this one based on its ability to maintain contact with the water for just that much longer as it followed the twist around the UV bulb. I would say that an extra 1/16th of an inch of plastic in the mounts would make this sterilizer absolutely perfect. When trying to snap the mounts onto the body of the sterilizer you actually have to fight with them, almost to the point of breakage to get them to fit. When assembling the bulb be sure to avoid touching with your fingers as the oils on your fingers will shorten the bulb life. All the seals and connections were tight and waterproof directly out of the box. However, I did not use the plastic nuts supplied to connect the tubing as they really didn't fit well or seem like they would do the job intended. I therefored used automotive hose clamps which maintained a watertight seal the first time. When looking for a pump to run the unit I choose the Eheim 1000 Compact Pump.

Burnt out bulb - short

Comments: This was my second TurboTwist. I had the smaller unit on a nano and then upgraded to the 12X on a larger display tank. The smaller functioned fine with no problems. The 12X lasted 4 months. After a cleaning I noticed stray voltage in my display tank and found that there was water in the bulb housing, I thought somehow water had gotten in after a cleaning. This time everything was dry and sealed and it worked for another few weeks then I noticed the indicator lamp was not glowing and the bulb housing was hot. I disconnected and found water again and that the bulb had short circuited itself. The bulb housing was burnt with severe corrosion. I am lucky it did not start a fire and that I had grounding probes in the tank else the livestock might have been killed.

Comments: This is the first UV unit I ever bought, and the reason was because I was starting to get alge. I wish I would of had this before an ick breakout that killed 5 fish...arghh. The reviews on it are spot on. Nice HD construction. I have it hooked inline from my canister, and the comment about the 1/2-5/8 connection is also spot on. I didn't use those connectors, instead bought some hose clamps to insure no leaking. I would recommend doing this if you have leaks.

Comments: I have given this product five stars, not only because of its performance and easy installation, but rather because of the superior customer service I've received. Once fully installed, I noticed that the lamp wasn't working. A brief call and they offered several solutions to replace the unit. I called the manufacture who within five minutes offered to ship me a new ballast at no charge. Although I shop at my LFS for water and marine life, I chose this store for all my hardware, for exactly the reasons I experienced this week. Thank you.

Comments: The 12X is perfect for those of us with large marine systems (200+ gallons). It is simple to set up, very user friendly, and bulb exchange is fool proof.

Comments: I purchased this to try and kill the parasites in the water after noticing my Naso Tang having lots of tiny white spots on him. I ran it for 3 days straight non stop and now my Naso Tang no longer has any white spot ich. So now I got it hooked up to my Reefkeeper and set up to a timer. It turns on for an hour at 6 am then another one hour at 6 pm. The product also looks heavy duty quality. However, I have to keep an eye on that rubber gasket for the hose connections because saltwater will eventually deteriorate the rubber and cause a leak. It made my water crystal clear too!

Comments: Let's face it, it is just a UV unit. No matter what unit you choose, the benefits are often not noticeable. If you have a tank that has good water quality and your algae is under control, you may not even see its affects. If you have a massive free floating algae problem, any properly (or oversized) unit will help to clear the water, but so would better husbandry. So, as for construction, the unit is a robust plastic and feels very solid. It's not a light plastic that flexes or feels weak in your hands. As other reviews note, the oring to hose adapter did leak at first. I removed the fitting and applied oring silicone, still leaked. Tried a third time and carelfully inspected the fitting, found a minor mold burr, corrected that and leak stopped. Minor in my mind but cost a half star in the rating. The other half star deduction was for the difficulty in the initial separation of the head from the chamber. I've wrestled various fixtures in the same way before, I wish the manufactures would lubricate the plastics and orings during assembly. Having said that, this unit was VERY difficult to get apart as it was assembled dry. I actually thought to myself, it's either going to break or come apart, either way the alignment did not work for me so I went for it. Hot water and strap wrenches were the final solution. It took a massive amount of force, so that reinforces my opening comments about the solid build (but you should be careful not to input the force against the inlet and dicharge mouldings, its reasonable/normal to think they would not take the force at all). Lubricate liberally when reassembling as you will need to clean the quartz sleeve periodically. In all, I purchased a UV unit to insure that the various prolific algaes that I culture in my refugium would not migrate to my display. I oversized and underflow that unit so that I can use my refugium as a quarantine station for new wild caught specimens without fear of introducing unwanted pests to my display. This unit will do all of that......
