Remove red slime from your corals and invertebrates. UltraLife Red Slime Remover is made up of natural cellular matter, select biological accelerators and supplements are proven effective in removing Red Slime.


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.

Note: For best results, DO NOT turn off UV Sterilizer or Ozonizer. Continuation of protein skimming is recommended, but may require adjustment.

Product Questions

Does this product have any sulfur in it? I'm starting red sea algae management, by dose pump, but can't use products with sulfur.
Question by: Donald on May 18, 2020, 8:30 PM
Hi Donald,

The ingredients of this product are not provided so I cannot say for certain if it contains sulfur or not. What I can say is that due to the small amount used when treating cyano it is very unlikely that an appreciable amount of sulfur would be added to the system should it be present in the product.

I hope this helps!
Happy Reefing

Hey for this red slime remover should i take out my carbon? also do i leave the filter sock in or take that out as well?
Question by: tyler chapman on May 16, 2017, 9:47 AM
There is no need to remove carbon during treatment. I would also continue to change out your filter socks at regular intervals.

Have a great day!
