ReVive Coral Cleaner 500mL - Two Little Fishies

ReVive Coral Cleaner is a surface-cleaning dip formulated by Julian Sprung of Two Little Fishies. Built on a plant extract base rather than harsh synthetic compounds, it is designed to cleanse the exterior of live corals and anemones without the tissue stress associated with more aggressive treatments. Its broad compatibility — covering stony corals, soft corals, zoanthids, and anemones — makes it a single solution for most of the organisms a reef keeper handles regularly.

The most common application is the acclimation dip. When new corals arrive from a wholesaler, shipper, or fellow hobbyist, a brief soak in ReVive helps remove surface contaminants, pests, and organic debris before the coral enters the display tank. This step is a meaningful layer of protection against introducing unwanted hitchhikers or pathogens into an established system.

ReVive also has a practical role in coral propagation. Facilities that regularly frag corals use it to rinse cut tissue before the frags are mounted or shipped, reducing the bacterial load at the wound site and supporting cleaner healing. It is equally useful as a pre-shipment rinse to reduce stress and surface contamination on corals being packaged for transport.

The 500 mL (16.8 fl oz) bottle is a workable size for hobbyists who dip corals periodically, as well as for small propagation operations that need a reliable supply on hand. As with any dip, follow the manufacturer's recommended concentration and soak time, and observe corals closely during and after treatment.
