RTN/STN X is a protective agent for corals and acts against tissue necrosis in corals (RTN/STN).
The special composition of this product interferes with developmental processes of the parasites and fungi involved and at the same time strengthens the corals’ defences.

  • Soft corals and sea anemones
  • Stony corals SPS/LPS
  • Azooxanthellate corals

We recommend a treatment period of 7-10 days.
If necessary, the treatment can be continued.

Before using the preparation, please note
