  • Blown Away By The Results!! Green Water Out, Crystal Clear Water IN!
This is a miracle pump. I've had aquariums on and off for the last 30 years and never have I seen this kind of algae bloom. I couldn't get rid of it. It was actually much worse than the "day 1" photo depicts. At the time I took that photo I had removed almost all of the decor due to having to do 50% water changes every 2 days. It was ridiculous. I didn't want to add chemicals that may or may not have harmed the poor fish that were already surrounded by horrible green algae ridden water. I did a lot of research online and this is the pump that was most recommended. After seeing a lot of photo reviews that greatly resembled my very green aquarium, I took a chance on it. I was extremely skeptical that a pump would eliminate the constant green water, but to my surprise it actually worked! I really wanted to do this review because nobody has mentioned using this pump for smaller aquariums. The listing for this particular pump says "for aquariums up to 75 gallons", it doesn't give specifics for small tanks; but I took a chance and tried it anyway as a last resort. My aquarium is a 5 gallon aquarium. They're very common in size and even 5 gallon aquariums can be subjected to the green water conundrum. This pump, even though it doesn't fit in my aquarium upright, it still fits lying down and is fully submerged. On day 1, I couldn't even see my fish unless they were at the front of the aquarium directly under the light. Day 2 wasn't really much different. I didn't think this pump would actually work, but by day three I could not only see the fish but I could also make out the heater on the back wall. My aquarium was clear enough by day 4 that I started moving my other aquarium decor back in. And on day 5 my aquarium was crystal clear. No green water, no traces of green water, and I can see everything in the aquarium including the wallpaper on the back wall. There were no chemicals added. I used this pump in my 5 gallon aquarium for 5 days and my water is more clear than it has been since this aquarium was established and cycled for the very first time. It's like a brand new aquarium and my fish are super happy. I don't know how or why this pump works, but it's pure magic. Having said that, this pump comes fully assembled. It includes oxygen tubing for aeration if you choose to do so. I didn't need the extra aeration so I didn't install that piece. It can be used 4-8 hours a day as the instructions suggest. I personally used this pump for 4 hours during the morning and again for 3-4 hours in the evening to get the results that I did. The results may vary given the size of your aquarium. I plan to leave this pump where it is for now. The instructions say once the water is clear you can reduce the time, so I'll leave it in the aquarium and gradually reduce the amount of time I use it. I did a 30% water change on day 5, AFTER that photo was taken and it was just to clean the gravel and debris from the standard aquarium filter. This green water killer pump is amazing and the results really do speak for themselves. I would have gladly spent twice as much money for the results that I got! It's truly unbelievable!! My fish are happy and their environment is healthy. I'd consider that a win! Highly recommend!! ... show more

  • Keeps Chicken Water Clean and Fresh
I bought the Internal Green Water Killer Aquarium Filter Tank U-V Pump to use inside my 5-gallon bucket chicken waterer, and it has been fantastic. Within just a few days, the water went from murky to crystal clear, which is essential for keeping my chickens healthy and happy. The built-in 5-watt water pump is powerful enough to keep the water circulating and fresh, and it's suitable for both saltwater and freshwater, which adds to its versatility. Even though it's designed for aquariums up to 75 gallons, it works perfectly in my smaller setup. Installation was straightforward, and it fits nicely inside the bucket without taking up too much space. My chickens now have clean, clear water all the time, and I don't have to worry about algae buildup or dirty water. Highly recommend this for anyone looking to maintain clean water for their animals or aquarium! ... show more

  • Works Perfectly!
This UV internal filter worked as advertised on my allege filled 75 gallon fish tank. It was very easy to setup and begin filtering. It took my green allege fish tank to crystal clear in five days! The main reason that I purchased this filter is because there are no additional “sponges” or filter medias within the housing. It is simply a UV light filter. The optional air hose attachment works very well for putting additional oxygen into the water. One thing to note about this filter is that it will kill all bacteria within the tank, good and bad. Once the tank got cleaned up, the filter runs four hours every other night. This filter is a very good, quick cleaning, inexpensive option for internal UV filters. ... show more

  • Takes time but works!
I have an African cichlid tank that has been going for almost a year now, normally I don’t have too much of a problem with this tank besides the fish making it a little cloudy from their ammonia they put off. One day I woke up and the tank was GREEN like bad as you can see in the photos, I tried algae fix, water changes, filter changes, almost anything you can think of and nothing worked. I had used something like this before on my community tank when it had a bad algae bloom and it worked pretty decent but the filter broke on me almost immediately after the tank was clean, so I didn’t wanna purchase that brand again. Although it’s only been 2 weeks with this one, it has cleared the tank up beautifully and is running great! There’s no noise it’s quieter than the regular filter. I definitely recommend this product if you have a bad algae bloom that you cannot get rid of! ... show more

  • Let me tell you how to make this work.
At first, it did not seem to work. I unscrewed the whole thing and did not see the light. However, I stuck it in the tank and it seemed to need a warming up period as it started to work after a while and the glow from the light appeared. One thing that was not intuitive is the little clear pipe. The end with the dial stays out of the water. Hang it over the side and outside of the tank. If you put it in the water the water being pushed through the machine stops. My water looks a lot clearer so far and hopefully soon my tank won't look like a crime against fish keeping. If you read all the way to the bottom of the instructions, it does say it may arrive wet as they test each one prior to sending it. So, don't get all mad like me before I read. ... show more
