Full Details

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 via the addition of airstones prior to and during treatment. No need for water changes or removal of carbon filtration.

Dissolve one level spoonful for every 15 gallons -- one container treats up to 300 gallons.

  • It works. Skimmer needs adjusting. By JADReefer on 10/25/2016

    I have suctioned red slime from my rock weekly for 4 months and never got ahead of it. I dosed Hydrogen Peroxide starting at 1 ml per 20 gallons of tank volume and increased to 1 ml per 4 gallons of tank volume over 1 week and continued that dose for 2 week. Along with the weekly suctioning It definitely helped but did not eliminate it. I dosed Ultra Life's Red Slime stain remover and it was gone in 48 hours. 3 weeks later it is still gone. After 3 weeks my protein skimmer is now back to full speed. It definitely makes your skimmer got nuts. It required multiple adjustments and several overflow experiences.
  • Best Prduct Ever By Kelly on 10/2/2016

    This product is amazing! I had red slime moving all over my tank. It had started getting on my coral and everything. It took two doses and it was gone. It's been three weeks now and I haven't seen any traces of any red slime. This is really an amazing product!
  • Worked great By Matt on 9/12/2016

    48 hours and it was gone.
  • perfect product By Rex on 7/7/2016

    Works perfectly, very happy w/ this product. It killed all red algae in my aquarium.
  • It works By Jason on 6/26/2016

    Easy instructions. Very effective. Like others have mentioned, just watch your skimmer to avoid an overflow etc.
  • Reliable product By Jason on 4/8/2016

    I seem to have a cyano outbreak each spring. I have a hypothesis that it may be related to the pollen here in the south, but this is just speculation because of the timing. Anyway, this product has cleared it up every time and it doesn't come back until the next spring. As others have said, the protein skimmer will go nuts. I found that if I turn mine off for several hours I can turn it back on and adjust it way down. If I'm home, I'll keep adjusting to keep it skimming efficiently as it calms back down.

  • Worked great By jeffrey on 11/28/2015

    Had a ton of red slime in my 240 gallon system . I used the whole bottle and slime was gone in about 2 days . It's been two and a half months and slime hasn't returned . Only down side was , I had to unplug the skimmer for about a week because it went absolutely crazy , but I would use it again in a heartbeat !! Thanks BRS !! 38 year hobbyist ! Jeff in Wisconsin
  • great product By dan on 11/9/2015

  • Works perfectly By Devin on 11/6/2015

    I have read the negative comments and i do not know why they had issues! When dosed as stated on the package, this stuff wipes out cyano in less then 36 hours! i would advise turing off your skimmer, not blasting corals with the solution, and adding an air stone for the time that it is being used. ZERO negative affects to corals, inverts, or fish!!! i did do a 25% water change just because, but it works amazingly!!
  • Didn't work! By Tbone on 10/26/2015

    Had a cyano problem on my sandbed, thought this might help out, did two dose's , absolutely nothing changed, I had used chemi-clean before and had success so maybe I'll go back to that stuff!!
  • supper By Mantas on 10/2/2015

    Wow. I had nasty red slime covering my sand bad. I was removing slime by hands every day and changing water twice a week and it didn't go away. It took two doses per two days of "Red slime remover" and all slime is gone. Gone and didn't come back
