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: (stopped working, how to fix) but amazing. - okay so I have NEVER done a review on desertcart.. 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.

Tried to manage it with more frequent water changes and leaving the light off becase the tank is in an area that gets some natural light but plants still suffered a bit. Got to a point that our fish couldn’t see their food flakes. The only plus is that our shrimp began to thrive since they weren’t being picked on by our betta. Put the device in and within 3 days the tank was pristine. Not sure if it’s also because we have two filters running in it right now, we’re trying to cycle one so that we can eventually remove the other. I am beyond happy with the result, saved us a lot of of extra water changes and less stress on our fish as a result. 100/100 recommend! ## Frequently Bought Together - COODIA Internal Green Water Killer Aquarium Filter Tank U-V Pump - COODIA Replacement UV Bulb Green Water Killer (2 Piece) - MICROBE-LIFT ALGAA08 ALGAWAY 5.4 Algae Control for Fresh and Salt Water Home Aquariums, 8 Ounces --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/143074155-internal-green-water-killer-aquarium-filter-tank-u-v-pump](https://www.desertcart.sk/products/143074155-internal-green-water-killer-aquarium-filter-tank-u-v-pump) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-30*
