Ultralife Red Slime Remover Information

Product Manuals & Documentation

UltraLife Red Slime Remover

UltraLife Red Slime Remover is a revolutionary time tested product, that will effectively and safely remove Red Slime quickly from all Coral and Invertebrates. UltraLife RSR contains natural cellular matter, select biological accelerators and special supplements proven effective in removing Red Slime from Corals and Inverebrates and is Safe for reef tanks, corals, invertebrates, desirable macro-algae, nitrifying bacteria and fish.

UltraLife RSR will accelerate the solubilization and biological digestion of organic solids. In the process, the oxygen uptake rate in your aquarium will increase as a result of this increased biological activity. It is very important that your aquarium is able to support this increased oxygen demand along with your aquatic life`s need for oxygen. Therefore we recommend increasing your O2 levels by the addition of airstones prior to and during treatment.

For best results, DO NOT turn off UV Sterilizer or Ozonizer. Continuation of Protein Skimming is recommended but may require adjustment.
Due to Increased biological digestion of organic solids we recommend increasing your O2 levels by the addition of airstones prior to and during treatment.
No need for Water changes or Removal of Carbon Filtration.

Safe for reef tanks, corals, invertebrates, desirable macro-algae, nitrifying bacteria and fish.

  • Treats up to 300 Gallons (1135 L) Net wt. .71 oz (20 grams)


. Powder type medication

. Will treat 250-300 gallons per bottle

Didn't work for me

Comments: I bought two, enough for 3 treatment protocols (two spread 48 hours apart, as per directions.) Even after removing most of the red stuff by blasting with a turkey baster and sucking or netting it out, it has returned. The treatments seemed to slow it up a bit, but it certainly did not clear the problem. Otherwise, I followed the dirctions regarding protein skimming and aeration. The good news, I guess, is that it didn't seem to harm anything else. Good luck.

Comments: Make sure you follow the directions carefully. Im fairly certain that almost anyone who used the Red Slime Remover and experienced a negative effect didnt watch their PH levels. I currently have my Apex setup and I monitor my tank constantly. Prior to dosing the Red Slime Remover I waited till the peak of my PH swing (in the afternoon) and added a PH buffer to bring it up to 8.3. Then I dosed the Slime Remover and watched my PH levels drop dramatically. So I let it stabilize at 7.2 and then checked my Alkalinity which was at 10.25 and then added a 1/4 dose of PH buffer. This brought it back up to 8.25 and it stabilized. I repeated the second dose of the Red Slime Remover 48 hours later with the same results. Its a great product if used correctly. I hope this helps and just a precaution you should never dose anything you cant test for.

Comments: I'm running a 24 Gallon Nano with both soft and stony corals, as well as a large-mantled clam, fish, and crustaceans. One treatment quickly eradicated the red slime problem that had arisen from poor flow in some regions (I also added a powerhead, but that only dislodged the slime in one area). Even the water column looks super clear! No creatures were harmed besides the slime.

Comments: Use this with the understanding you can deplete the oxygen levels easily. Use airstone, and do NOT overdose. I speak from experience, I just lost everything in my 14 gal. Bio cube because I didn't think I needed to oxygenate the tank. I'm not sayIng avoid this product., it does a good job of removing red slime. I would consider water changes and work on keeping the temp below 80. Temp fluctuations are the primary cause of red slime. In my area (Florida) it seems it gets worse around Nov. and Dec.

Comments: i have a 72 bow with 20 gallon sump. i used 5 scoops, each scoop treats 15 gallons. i figured my rocks and sand took up some water voume and my sump is 9 inches high out of 16 inches depth so i only have approx 11 gallons in sump. i left my lights on and i took collection cup of skimmer and opened gate valve all the way open. expect a ton of foam/bubbles in sump. the medication took the full two days to work. after you do a water change 48 hours later throw a filter sock on and your collection cup back on. it will skim super wet for two cups but then it will settle down some. dont use filter sock for more than a day. you will have to clean your skimmer neck and cup because it leaves a slimey haze on it. your corals wont like it at all, especially the lps and sps. it took four ten gallon water changes and 4-5 days for everything to start looking good again. it will turn your sps white but dont worry, the polyps will slowly start to come back. it didnt seem to bother a large favia brain at all or any of my polyps and palythoas. green tyree toadstool finally starting to come out again about a week later. tank started a small cycle of diatom on the sand in places. all the fish seem fine and i didnt lose anything. i admit i wasnt keeping up on water changes. i dont want to go through this agian so i will keep up on water changes. also change your ro/di filters or get a tds meter so you know

Comments: For months, I had been fighting a losing battle against cyano in my BC29, using traditional techniques. In desperation, I tried this product, and it completely wiped out the cyano in about 48 hours, without harm to anything else in the tank. Per the instructions, I added an airstone, but left adsorbent media (carbon, GFO, Purigen) in place. On day one, the water was yellow from adding the product. By day two, the cyano was dramatically diminished, and the water was a pinkish hue, with the skimmer pulling a large amount of gunk. By day three, the water was clear and the cyano had vanished. The amount of product in the small bottle provided would appear to be practically a lifetime supply; a little goes a long way.
