Review: ¡Un clásico marino! - Tengo cuarenta años manteniendo acuarios marinos de todo tipo, Instant Ocean y la sal que de las salineras de Lorena, Francia obtienen con adición de sintéticos me ha acompañado todo ese tiempo sobre todo cuando hay épocas en donde requieres un precio económico, ya que la acuariofilia marina no es para cualquiera por los costos que en cualquier momento enfrentas, el contar con sal de emergencia es obligatorio y desde siempre he contado con bolsas de reposición sin importar cuando las use, de tener hace unos veinticinco años un tanque de 1,000 GA pase gradual y lentamente a los tanques NANO con el ahorro en recursos, energía y especímenes para ir de la mano con una política de planeta sustentable y ahí estuvo Instant Ocean y seguirá hasta donde mi afición me lo permita. Review: Very for price, - Been using this line of salt from instant ocean for about 2 years now, very good product and the salinity instructions on the back are very accurate, ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Instant Ocean | | Item form | Granules | | Item weight | 6.8 Kilograms | | Liquid volume | 50 Gallons | | Manufacturer | Instant Ocean | | Unit count | 240 Ounce | ## Product Details - **Brand:** Instant Ocean - **Item form:** Granules - **Item weight:** 6.8 Kilograms - **Liquid volume:** 50 Gallons - **Unit count:** 240 Ounce ## Images ![Sea Salt (50 gal)_MB - Image 1](https://m.media-amazon.com/images/I/81K3I-LMf1L.jpg) ## Questions & Answers **Q: Why the crazy price hike?** A: Crazy, I just ordered this 5 gal. bucket ( 160 gal ) and the price almost doubled ? Sooo, I drove a few miles to buy at Petco for about $40.00 w/tax, " Come on Man " **Q: Can you use this for hermit crabs?** A: Yes, you can use this to make drinking/soaking water for tropical land hermit crabs. Just be sure they always have TWO WATER DISHES - one with de-chlorinated fresh water and one with brackish or salt water such as this. The dishes need to be deep enough for them to fill their shells with water if they want, but must have sponge or some driftwood in them for easy access in and out. Few people realize they need salt water as well as fresh, kudos to you for inquiring! If you know which species you have, you should google to find out any specific quirks or requirements. **Q: Ratio (ingredient weight to water volume) for brackish water condition?** A: Typically, we recommend starting with 1/4 cup of salt to one gallon of water. This is half the amount used to make full marine conditions. You will need a hydrometer or refractometer to test the salinity. You need 1.010 - 1.015. **Q: If I have a 39 gallon tank, what size should I buy?** A: You'll always need to make water for water changes so buying in bulk saves money. if you go to the web site it will tell you the exact amount per gallon ## Customer Reviews ### ⭐⭐⭐⭐⭐ ¡Un clásico marino! *by I***A on 2 February 2026* Tengo cuarenta años manteniendo acuarios marinos de todo tipo, Instant Ocean y la sal que de las salineras de Lorena, Francia obtienen con adición de sintéticos me ha acompañado todo ese tiempo sobre todo cuando hay épocas en donde requieres un precio económico, ya que la acuariofilia marina no es para cualquiera por los costos que en cualquier momento enfrentas, el contar con sal de emergencia es obligatorio y desde siempre he contado con bolsas de reposición sin importar cuando las use, de tener hace unos veinticinco años un tanque de 1,000 GA pase gradual y lentamente a los tanques NANO con el ahorro en recursos, energía y especímenes para ir de la mano con una política de planeta sustentable y ahí estuvo Instant Ocean y seguirá hasta donde mi afición me lo permita. ### ⭐⭐⭐⭐⭐ Very for price, *by A***W on 14 April 2026* Been using this line of salt from instant ocean for about 2 years now, very good product and the salinity instructions on the back are very accurate, ### ⭐⭐⭐⭐⭐ Buen precio *by H***D on 21 January 2024* Llego rapido y a buen precio, gracias! ## Frequently Bought Together - Instant Ocean Sea Salt 50 Gallons, For Marine Aquariums, Fast Dissolving - API SALTWATER MASTER TEST KIT 550-Test Saltwater Aquarium Water Test Kit --- ## 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.co.za/products/266531102-sea-salt-50-gal-mb](https://www.desertcart.co.za/products/266531102-sea-salt-50-gal-mb) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-04*
