Fauna Marin Reef Fix is a specialized, fast-setting cement designed for permanent aquascaping and secure coral mounting. Unlike standard epoxy putties, Reef Fix is an extremely pure, mineral-based cement that bonds and cures effectively even underwater. It is engineered to promote the rapid colonization of coral tissue and coralline algae over the bond site, making it the ideal choice for creating complex overhangs, caves, or custom frag rocks. Tested in the Fauna Marin ICP laboratory, it is guaranteed free from heavy metals, silicates, and chromates, ensuring 100% safety for the most sensitive reef systems.
Reef Fix provides a structural foundation that allows for more creative and stable reef designs.
Underwater Curing: Specifically formulated to adhere strongly to wet rocks and corals, allowing for "in-tank" construction without draining the system.
1-Minute Setting Time: Hardens extremely quickly (approx. 1 minute after kneading), reducing the time corals need to be held in place and minimizing stress.
Promotes Biomineralization: The special mineral blend encourages coral tissue to grow over the cement faster than traditional glues, creating a natural look.
Custom Frag Creation: Can be mixed with coral sand (2:1 ratio) to create customized, natural-looking frag plugs or "spin-off" stones.
Laboratory Grade Purity: Free of unwanted trace elements and heavy metals, preventing any negative impact on water chemistry or sensitive SPS corals.

Can I use Reef Fix to glue rocks directly to the aquarium glass?
Yes. Reef Fix has excellent adhesion properties and can be used to secure decorations or rocks directly to glass surfaces, though caution should be used to avoid scratching.
Is it safe for my fish and invertebrates?
Yes. Reef Fix is 100% reef-safe and does not leach harmful substances into the water. However, like all cements, it is alkaline during the mixing phase; always wear gloves to protect your skin.
How do I prevent the cement from hardening too fast?
Always use cold water for mixing. Warm water will significantly accelerate the hardening process, leaving you with very little working time.
Can I use this for large aquascaping projects?
Absolutely. Its high structural strength makes it perfect for bonding large pieces of dry reef rock or live rock to create stable arches and overhangs that wouldn't be possible with standard reef glue.
