Coralife 05741 3X Turbo Twist UV Replacement Lamp, 9-Watt

These bulbs do what they are supposed to. When they are on and there is adequate water flow through your UV sterilizer, you should be free from algae and bacteria which discolor your water. I use it on a 55 gallon FOWLR tank and it always does its job. The only problem is the short life span. It doesn't get nearly the 10,000 hours which it claims to. I would say I have averaged about 4-5 months per bulb over the past 4 years of using this UV sterilizer. This can start to get somewhat expensive and time consuming to always replace the bulb. Also, unless you check the bulb regularly, it may burn out and you and you won't realize it until there is a problem.

Overall: works well but doesn't last long enough

Within few days the lamp worked and our pond is clear. I love being able to see my fish swim around...

I'm not super happy with the life of these bulbs. That said, they do the job, and the Turbo Twist units are great.

If you're thinking about running UV continuously for the sake of general water purity, consider that it's not necessarily to do so with most aquaria. We ran continuous UV for awhile but found that replacing our carbon with Seachem Purigen worked as good or better at removing organic impurities in our water. Purigen polishes the water amazingly well, even where some algae is present. Plus, it's renewable and lasts 5-10x longer than carbon. Now we only use UV if one of our pets is ill (rarely), which keeps us from buying UV lamps every few months. It's sooo much less expensive this way.

This lamp is a true replacement product for the Turbo Twist UV sterilizer. Easy enough to install. My only complaints about these bulbs is that if run continuously (as they should be), they only last around 6months. If you are currently using this product, be sure to purchase a spare and keep an eye on the bulb as it will need frequent changes. Good luck!
