Blue Green Slime Stain Remover

This stuff works. I don't care what anyone says. I learned to just use aquatic animals to get rid if algae but 100% this works if you cant take that route. I gave my friend some of this stuff to get rid of the pink algae in his cichlid tank. It was gone a few days after using this product. Seems safe for fish and snails. Didnt have any issues when I dosed it for green slime algae either. It ate that stuff away in a couple days and I could just blow it away. Wallah magic. It never came back. Will likely buy more to keep it on hand.

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.

I fought with this Blue Green / Cyanobacteria for about 3 months. I followed every hot tip I could find on the web and was in the tank multiple times a day doing physical removal. The ONLY thing that worked was this product right here. I have two tanks and I lost zero fish, plants, snails, or fry. Completely dissolving the dosage takes a few minutes and it took two doses (a mere fraction of the amount of product you receive), and within the first 2 days a dramatic change happened. All the spreading stopped, the carpet layer turned brownish and was able to be siphoned out easily. 25% water change between doses and a 50% water change and thorough gravel cleaning is what i did for my results. Thank you for providing this life saver!

I have a substrate that contain nutrients and some unknown ability to harbor blue-green algae. (65 gallon tank/fresh). I have used erythromycin that only eliminates obvious growth of the algae, only to have it return in a week or so, now with a somewhat resistant strain that survived the medication. I have also used ozone that does destroy this algae so it is not to be seen, but it apparently is still alive in the substrate because the blue-green algae returns. Other than breaking down the tank and cleaning the substrate, the only recourse I had was to use this product, a chemical. I still do have blue-green algae, but it's ability to thrive and reproduce has been diminished considerably, to the point where little remains. This product was introduced 2 months ago and multiple doses were administered. Time will tell how much of this algae will be eliminated altogether. pros: it will control blue-green algae, and perhaps eliminate it, depending on the type of substrate used and items in your tank (driftwood, plants, etc) con: don't expect miracles, and the algae might not be eliminated, depending on your situation I have purchased this more than once, and would recommend it Edit July, 2018: I cannot give this product a 5 since in my experience, it required a two punch treatment. The algae came back after a while. So I tried excel. I found that both of these used together, one after the other, works long term.

My tanks were really struggling with blue green slime. I had gotten down to 5 hours of light a day on my 10gal tank and tried increasing flow via an airstone and increasing nitrogen with a plant supplement but nothing seemed to be working. There was always a thin layer of this stuff on everything. I put in the recommended dose of this stuff. After the first 24 hours not much had changed at all, if anything. Day 2 though, SIGNIFICANT change. The BGS is still there, but it's getting stringy and "dissolving" for lack of a better word. Day 3 there's actually less of the stuff, it's gone completely from the substrate, only managing to stick around on some plants and wood. I'm giving it a full week before redosing - but this stuff works fast. The bottle is very small, but you use and extremely small amount to dose a tank, so it should be plenty unless you're working with more than 100 gallons. I have nerite snails, ramshorn snails, otocinclus, and a betta in my tank and none of them had any issue with this stuff. I would say it's plenty safe for snails and plants.

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.

The sand in our tank was getting really gross with blue-green slime. This completely resolved the issue without harm to any plants or critters.
