So I'm sure they send you fresh packed sand. I completely recommend it. **Q: what is special grade?** A: The title is confusing on this item as "Special Grade Reef" and "Fiji Pink" are two totally different types of sand. Both are nice but the Special Grade is a bit bigger, if you go to there website you can see the differencehttp://caribsea.com/pages_caribsea/page_product_aragalive.html **Q: My ammonia didn't spike at all. live rock is in, did your ammonia spike with this sand?** A: This is supposed to cycle your tank instantly... if you have an ammonia spike then you need more live rock. The bacteria in this acts as a filter **Q: Can it be used for fresh water** A: You can use this for freshwater but it will kill the bacteria, but the sand would be fine to use. the one drawback though is it is aragonite sand, so a lower ph it could dissolve some and add too much calcium in your water. For saltwater you actually want some calcium to dissolve for the corals, but i don't think extra calcium would hurt anything in freshwater. ## Frequently Bought Together - CaribSea Arag-Alive 20 lb Fiji Pink Sand - Instant Ocean Sea Salt (50 gal)_MB --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/254556135-carib-sea-arag-alive-20-pound-fiji-pink-sand](https://www.desertcart.us/products/254556135-carib-sea-arag-alive-20-pound-fiji-pink-sand) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-09-04*
