RTN STN X Rapid Tissue Necrosis Treatment

Fauna Marin RTN/STN X is a coral-care preparation marketed for use when coral tissue is receding. The X formulation is applied to aquarium water using a defined treatment schedule, with instructions that differ from a separate coral dip.

Investigate water stability, damage and other possible causes of tissue loss alongside any treatment. Follow the X product's instructions for activated carbon and equipment operation, and observe the corals throughout use. A product name does not establish the cause of tissue recession or guarantee recovery.
