Ultralife Blue Green Slime Stain Remover

First, this product is amazing! Now read my story on why it's amazing. Trust me it works. After a long absence from the hobby of freshwater fish, my wife and I returned about a year and half ago. With a little bit of re-learning curve, the tank was doing great for a year almost. We have a happy bonded pair of EB Acara that breed regularly, a happy and large Clown Fish, several Rams and lots of Julii Cory--along with snails and other fish. It all was going so well with regular maintenance, feeding them frozen worms and brine shrimp everyday, good water quality, no lose of life, pretty live plants...our tank was awesome! Then it happened. Not sure why or how. And after HOURS of research and talking to the LPS folks, still no clearer answer was found. And nothing I did could fix this ugly Blue-Green slime covering everything in the tank. I tried it all--all the advice of experts. I did large water changes, cleaned all the plants with 3% Hydro-P and I would get the tank green free and BAM! the gross green slime would return quickly. I did everything suggested--more light, less light, new lights, more chemicals, less chemicals, more cleaning, anti-Algae treatments, less food, different food, different canister filter set-ups, and on and on (some of the attempts were pretty expensive too)... nothing worked. I mean Nothing At All. I was very close to throwing in the towel completely. Research shows the number 1 reason why people leave this hobby is Algae. That was almost me. But finally one night after giving it one more shot and looking around on the internet I discovered that it is NOT Algae after all, but instead a bacteria. Called Cyanobacteria - Blue-green Algae (but its no Algae). So armed with this new information I stumbled onto this product on the hobby blogs and looked here on Amazon and read the reviews and looked at the pictures. Shocked I saw the exact same problem in those photos that we had! So I ordered UltraLife immediately. And I'm very happy to report two weeks later it is all gone. No more Blue-Green Slime and as an added bonus my tank looks almost new again. All the live plants look healthier, the stuff in the tank looks cleaner and the sand on the bottom looks almost new again, the downed Zero is clean again. I am so thankful for this product! It actually changed my life and made me happy with the hobby that we have literally way over a thousand dollars invested in. And to think, I was about to throw it all away! As the great reviews I read here said, why this product is not on the shelf of every LPS and major pet store chain is beyond me. Another reason why I guess I do almost 90% of my shopping here on Amazon. Anyway, if you have a bright green slime that looks like green Algae, it is not and to get rid of it completely -- use this amazing product, nothing else works, trust me. I simply took a large 2 liter bottle of UV freshwater sold at the nearby chain pet store, mixed in half the powder from the little bottle of UltraLife and let that sit for a few hours. Then I poured into my 80 gallon tank. Nothing happened at all for a few days, but then I could see it working some. It was breaking down and destroying the Blue-Green slime. It almost got it all after a week, but my tank was bad off. So I did a small water change and then repeated again. The rest of the small bottle of powder in another 2 liter freshwater UV purified store bottle and into the tank after it dissolved. Now another week later it is all gone and the tank looks great! In the picture I've attached its gone. But just a short two weeks ago almost the entire bottom was covered in a really bright green slime. It was all over the plants, the downed Zero plane, and on the heater, the Co2 diffuser, the bio sponge filter, etc. -- no its completely gone! I will always have this product on hand for now on. Try it, it works and its amazing.

I have a 10-gal tank that I suspect got seeded with this "green slime" bacteria during the addition of some new fish about six months ago. The water seemed unusually cloudy for several days and then over the next month everything steadily became covered with bright green algae-looking stuff. The tank also started to emit an earthy pond-water odor. I was periodically pulling the stuff off the tank bottom and the plants to try to keep them from being totally choked out, but I clearly needed to take more aggressive action to stop the stuff. I read a number of reviews and opinions, and this product looked like the best combination of safe and easy. The manufacturer is very vague about what it's actually made from, but it appears to be a biological extract, not a chemical or pharmaceutical compound. About three months after the suspected seeding event, I did an initial dose following more manual de-sliming. I followed the instructions carefully for the amount and process of dissolving in warm water, etc. I was hoping to see what some others had described, where the slime was clearly dying and disappearing within a few days, but after a week all I noticed was a slow yellowing in certain areas. The instructions mention re-dosing, so at that point I did a second round. The yellowing continued into a light brown, but the dead biomass never really disappeared. The fish and shrimp seemed uninterested, so apparently it doesn't taste as good as actual algae. Eventually, about a month after the initial treatment, I declared the operation complete and spent an evening rubbing dead slime off various surfaces and vacuuming up the debris. Perhaps most importantly, it hasn't returned in the couple months since, something a few others had described with frustration. In conclusion, I think this is probably the best treatment option out there, as it did stop the slime and had no apparent side effects on the fish and plants. Just beware that the die-off may occur slowly over a few weeks, and you should expect to clean up some debris after treatment. I will also mention that the instructions say to increase aeration during treatment, perhaps expecting that the decay of dead slime may deplete oxygen levels. My only aeration normally is a HOB-filter, and I didn't really want to buy a pump and air stones just for this exercise. So, I ran the initial couple weeks of treatment with the water level a couple inches low to create more splashing from the HOB waterfall. Minimizing oxygen demand was also a motivation for my thorough manual slime removal at the time of the initial dosing. Not sure which of these was more important, but I didn't have any deaths or notice other fish stress during the treatment period.

Review: Effective Blue-Green Algae Remover – Worked Within Days! I was dealing with a pretty persistent case of blue-green algae in my aquarium—it was covering my substrate and creeping onto the plants. After trying to manage it naturally with lighting adjustments and water changes, I finally decided to try this blue-green algae remover, and I’m so glad I did. Within just a few days of using it, I saw a noticeable difference. The dark, slimy coating started to break up and disappear, and the water looked clearer. I followed the dosing instructions carefully, and it didn’t affect any of my fish, shrimp, or snails, which was a big concern for me. Everything in the tank handled it great. Now, a week later, the tank looks almost brand new. The plants can breathe again, and I’m not fighting the constant spread. This remover did exactly what it claimed to do—and fast. Highly recommend it if you’re dealing with BGA and want a reliable, safe solution.

Long detailed review ahead.... This stuff works miracles. My tank was overgrown with blue green algae. It was on the rocks, the plants, decorations, everything. I would scrape the tank, move the substrate, frequent water changes and was never able to get it under control. I read every forum online and found this stuff. Here’s exactly what I did to completely eliminate the algae from my tank. 1. Increase airflow in the tank. I added an air stone. 2. Dose the first does of blue green slime stain remover. I did not clean the tank in any special way before adding and kept notes of the day I added and took pictures to see the change. 3. Feed fish like normal and watch. At the 48 hour mark, I could see the tank was getting a little cloudy and the algae was doing something. It wasn’t going away so I added the second dose 4. Keep watching the tank and feeding fish like normal. I didn’t do any water changes during this time but there was clearly something going on. The tank started to get cloudy and the sponge filter was clogging up every day or two. I Would rinse the sponge and put it back in when needed. 5. One week after the second dose, the tank was starting to clear but not so much to where everything was gone. I performed a water change at this time, and also took out all decorations and cleaned them of the algae. I gravel vac’d the full tank and put everything back. I did not dose again after this water change. There were still signs of algae on the substrate but I was pretty happy with the results. Tank was still a little cloudy but I figured the product would continue to do its job. 6. Keep watching the tank. Over the next 2 weeks the tank continued to slowly rid itself of the algae. The sponge filter kept getting clogged and I kept cleaning it out to allow it to do its thing. At this point I returned to weekly water changes and gravel vac but no more decorations to clean as they have no signs of algae. 7. Enjoy your clean tank. Today is exactly 3 weeks from the first dose and my tank has zero algae growing in the tank. The substrate slowly rid itself of the green and water is clear. Now I’m not sure if every case will be like mine, but this stuff seriously impressed me. I am glad I have some extra in case I need to dose again at another time but anyone who has this blue green algae issue needs to have this stuff in the fish cabinet. TLDR; Stuff works great, be patient, I seriously recommend this product.

I don’t know what’s in this stuff, but it is magic! I went through so many options that nearly killed my fish but THIS is the only one that has worked. The pictures are of first night of treatment, and 2 days later. Absolutely no reaction from my fish. Though, I will say I advise users to use an air stone for a few days after using this, as it can reduce DO levels. Three weeks on treatment and my hassle of having to deep clean this tank every week is gone. The only leftover of the cyanobacteria is in the substrate (this is why I put 4 stars), but it’s a HUGE improvement. BUY THIS!

This stuff works! It got rid of blue-green algae immediately and with the first dosing. It was bad. I was struggling with it in my aquarium. I took a chance on UltraLife Blue-Green Slime away because of the reviews. It worked. My tank look really clean. Btw.... I am religious about doing weekly water changes and the tank still got a blue-green algae infestation so just saying... this is a good item to have on hand for your aquarium maintenance.

I join the chorus. This stuff really works very well. I had a bad case of blue green slime algae. Now, just like many of us, I assume, I thought it was algae. For those who are not sure if they have this algae (that actually is not an algae) here is how to find out if you have blue green slime algea (cyano bacteria) or any other type of algea: 1. It grows back really fast after you cleaned your tank. 2. It forms a slimy layer over driftwood or plants, that can be removed pretty easily (opposed to hair algae). 3. But: most easy way to tell: your tank water really smells bad, like old pond water. That is easy to tell. Do the test: stick your hand in your tank water, then wash your hands with soap. Then smell your hands. If still smell (even remotely) the tank water on your hands: yes it is cyano bacteria. Now the good news. This stuff works. But be smart and treat your tank exactly according to the instructions. First of all, calculate your gallons of water correctly. If you have a fifty gallon tank, but lots of driftwood, stones, and gravel and plants, your may have only 40 gallons of water. So dose this stuff correctly. On day one: clean your tank thoroughly and do a big water change. Then dose the amount of powder precisely and dissolve it in some aquarium water. Then poor in slowly. Day two: you do nothing. Day three: exactly 48 hours after your first dose, you dose again, same amount. Then wait a FULL week. No water changes, no nothing. Just wait. In my tank it really kicked in on day 6 and 7. Smell is 100% gone, the slimy stuff disappeared completely. Now, at this point I was in doubt if I should do the cycle again after a big water change, to make sure the bacteria was gone. But my tank is so clear and clean, that I decided against it. If the bacteria returns, as they may ( other reviewers mentioned this stuff is 3 billion years old), I know this product will save me again. I hardly ever review a product. But before buying anything on Amazon, I always read reviews and I am thankfull to people taking the time to write a good and honest review. So today I decided to write this, because I am 100% satisfied. Again, It is today 9 days ago I started the treatment, but the results are unbelievable. It may come back, as other algae types can, or diseases like Ick, or any other bad luck. Hope this long story helps others in the hobby that are desperate and about to give up. Take care y'all. Greetings from Texas.

Worked great! Highly recommend.
