Seachem Flourish Epoxy
The Seachem Flourish Epoxy is a two-part putty adhesive that lets you build and secure your hardscape both above and below the waterline. Knead the two components together and press the putty around contact points to lock rock, driftwood, and stacked stone into stable, natural-looking layouts, or to fasten rhizome plants and coral frags in place. It cures underwater, holds firmly, and is completely safe for fish, plants, and invertebrates. Pair it with Seachem Reef Glue for quick spot bonds and browse our aquarium plants to complete the scape.
Features

- Secures rock, driftwood, and stacked stone for stable aquascapes
- Great for mounting rhizome plants, moss, and coral frags to hardscape
- Safe for fish, plants, and invertebrates in freshwater and saltwater

How to Use
- Cut off the amount you need and knead the two layers together until the color is uniform.
- Press the putty firmly around the contact points you want to join.
- Hold or brace the pieces while it sets. You have about 5 minutes of working time.
