Title: Blown Away By The Results!! Green Water Out, Crystal Clear Water IN!
Review: 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!!

Title: (stopped working, how to fix) but amazing.
Review: okay so I have NEVER done a review on amazon.. ever lol. But I felt the need to make this review. So I used this thing for a day and turned it off, and used it the day after, turned it off and just did every other day with this thing on This thing worked wonders, for real.I left it in the bottom of my fishtank for a few weeks because it did not need attention and I tried to use it a few weeks/months later and it wouldn't turn on. I found out that I had to unscrew and clean out the little algae knob. After I did that, I plugged it in and used it for a few days straight and it worked beautifully. It makes my fish tank so extremely clear. Whenever my tank is acting up I throw this sucker in there and it gets rid of all algae or diatoms. I didn't cover my tank up either but I tried to not let it have direct sunlight but I dont think it matters if you do. I have coral in my tank so I had to turn the lights on for at least 9 hours a day. I highly recommend this product and it's seriously the best for the price. It works wonders frfr

Title: Best Way to Kill Algae!!
Review: Works Amazing! Be patient! I ordered this product after fighting with a green haze in my tank for 9-monts. I tried multiple water changes, algicides and filter changes. I even emptied and cleaned the whole tank, nothing worked or it just came back. I bought this item a last-ditch effort. At first I did not see much change. Just as the product was advertised it will take 7-10 days. After 10 days the tank is crystal clear! I am finally happy to have a clean fish tank and it is all thanks to this product.

Title: Works Perfectly!
Review: 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.

Title: Too big for a 10G tank, but very effective
Review: This filter barely fits upright in my 10G tank. It's a better fit sideways, but that made it harder to fit my tank decor around. But it absolutely worked to make my water crystal clear. 100% works as advertised, just make sure it fits in your tank. Will probably work fine in a 20G or larger. Or if your 10G tank doesn't have any other stuff in it.

Title:
Review: Product looks great but I wouldn't risk plugging it in as it does not appear to be dual voltage. Please include the voltage rating on the website and stop selling this in the UK before you cause an electrical fire. A stepdown converter will cost as much as this product and be noisy. The actual component looks good I just dont think Amazon should sell it in the UK.
