Review: Great if you know how to use it - Ive used Nyos and Marco cement for building aquascapes. Compared to Marco, Nyos mixes up smoother and the end result is more clean. You need to mix it 3 parts powder to 1 part water. If you add some citric acid to the water you can extend the working time. You have to mix small quantities at a time and use a spatula or backnof a spoon to incorporate the powder with the water. Wait until it gets doughy before you try to add it rock otherwise it will be to loose and fall away from the rock. When the mixrure starts heating up (exotherming) you have to work more quickly. Marco cement gives you more time but sets up grainy. Review: Good product - Works perfectly for me. I glued big stones that I took from aquarium.

Works fast and reliable ### ⭐ Waste of money for wet application *by K***K on 21 April 2026* This product does not work as advertised. You can not use it on wet rock. If you try to apply it to the rock or coral plugs it just degenerates in the water. I waited to long to use it now I'm past the return window. Don't waste your money if you want to use this on wet rocks or frag plugs ## Frequently Bought Together - NYOS Reef Cement - 500 ML - Instant Ocean HoldFast Epoxy Stick, Fish Safe 4 oz - Seachem Reef Glue Cyanoacrylate Gel Coral Frag Mounting, 20g (001167) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.de/products/67141480-nyos-reef-cement-500-ml-by-nyos](https://www.desertcart.de/products/67141480-nyos-reef-cement-500-ml-by-nyos) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-27*
