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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ buena *by C***E on 2026年4月7日にメキシコでレビュー済み* el producto llego bien empacado y la arena es un poco fina pero se ve bien ### ⭐⭐⭐⭐⭐ Lovely colour *by A***N on 2025年4月14日に英国でレビュー済み* Looks really great in the tank can't wait to get fish in there ### ⭐⭐⭐⭐⭐ great sand *by V***V on 2025年2月17日にアメリカ合衆国でレビュー済み* great sand!! thank you. no need to rinse with rodi water. cloudy water will go away fast if and only if floss is used. both of the nano tank water cleared in about one day. the cloudy water is really crushed sand. the sand is crushed during packaging and shipping. no need for reef carbon, purigen and phosguard when cycling new aquarium. some people use dry sand and dry rocks to start a new saltwater aquarium. please do test the aquarium water for nitrites, nitrates and ammonia for two months. the dry rock, dry sand method will take 60 days for the aquarium to cycle. then add filter media and cleanup crew ie. snails to the saltwater tank. make sure ammonia is zero before adding fish and cleanup crew. some hobbyists use real saltwater, live rocks and live sand. add add benificial bacteria with fritz turbo start 900 will help either way. both our tanks cycled fast with live rocks, live sand and real ocean water. livestock was added a few days later. and only after testing the aquarium water to ensure the aquariums was safe for fishes and a cleanup crew. both pairs of black snowflake extreme clownfish love it in their nano tanks. we used caribsea fiji pink sand and live rocks with plenty of coralline in the two nano tanks. coralline are the purple algae on the live rocks. coralline algae comes in many colors such as pink and purple. aquarium lights such as kessil are great for live rocks and coral, however, only ambient room lights are currently used to light both aquariums. the purple coralline on the live rocks will get lighter in color and the purple and pink colors in all likelyhood will fade without aquarium lights, however, the helpful and needed bacteria will still be alive. never leave the aquarium lights on for extended periods of time. do not keep the aquarium lights on for too long a period of time. in addition, overfeeding will cause the aquarium water to be nutrient rich for green hair algae, algae and cynobacteria better known as red slime algae. all saltwater aquariums have ugly stages. some hobbyists use a uv sterilizer to help with algae and ich. patience is needed for this hobby. water tests and at least three months are needed before adding easy corals. never introduce too many fishes to an aquarium. always do weekly or biweekly water changes. always use rodi water to topoff the evaporated water in the aquarium. never use tap water for aquarium water evaporation. always go slow. and read and post questions in saltwater aquarium forums. ## 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/767685276-caribsea-arag-alive-20-pound-special-grade-reef-sand-fiji](https://www.desertcart.us/products/767685276-caribsea-arag-alive-20-pound-special-grade-reef-sand-fiji) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-14*
