Do you want a healthier living environment for your lovely fish? Then make your decision to purchase this Green-Killing-Machine Review: 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!! Review: Bad product - Dont buy it !! Its not worth your money the material is not that great (feels cheap) plus its 120V with US plug the seller doesn’t say it so be careful. ## Features - Turns green water to clear in 3 to 7 days. - Suitable for Saltwater and Freshwater - Clean up to 75 gallons tank - Built in 5 watt water pump - 5 Watt U-V bulb included ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07V26V5MS | | Best Sellers Rank | #72,703 in Pet Supplies ( See Top 100 in Pet Supplies ) #4,521 in Aquarium Accessories | | Brand | COODIA | | Brand Name | COODIA | | Color | Green | | Colour | Green | | Customer Reviews | 4.2 out of 5 stars 6,981 Reviews | | Manufacturer | COODIA | | Manufacturer Part Number | OZJONG | | Material | Stainless Steel Polypropylene (PP) Polycarbonate | | Material Type | Stainless Steel Polypropylene (PP) Polycarbonate | | Model Number | OZJONG | | Number of Packs | 1 | | Power Source | Corded Electric | | Power source | Corded Electric | | Product Style | Industrial Green Submersible | | Specific Uses For Product | Aquarium maintenance | | Style | Industrial Green Submersible | | UPC | 667016085119 | | Unit Count | 1 Count | ## Product Details - **Brand:** COODIA - **Colour:** Green - **Material:** Stainless Steel Polypropylene (PP) Polycarbonate - **Power source:** Corded Electric - **Style:** Industrial Green Submersible ## Images ![Internal Green Water Killer Filter Aquarium Tank U-V Pump - Image 1](https://m.media-amazon.com/images/I/51MFBPxYGyL.jpg) ![Internal Green Water Killer Filter Aquarium Tank U-V Pump - Image 2](https://m.media-amazon.com/images/I/71IEC2fOSsL.jpg) ![Internal Green Water Killer Filter Aquarium Tank U-V Pump - Image 3](https://m.media-amazon.com/images/I/71AN+g0VtJL.jpg) ![Internal Green Water Killer Filter Aquarium Tank U-V Pump - Image 4](https://m.media-amazon.com/images/I/51XmHBoD8XL.jpg) ![Internal Green Water Killer Filter Aquarium Tank U-V Pump - Image 5](https://m.media-amazon.com/images/I/71jEYjo5yLL.jpg) ## Questions & Answers **Q: What does this do to beneficial bacteria?
