Frequently asked questions

To mix Instant Ocean Sea Salt for your aquarium, first ensure you have the right amount of dechlorinated or reverse osmosis water for the volume you want to prepare. For a 50-gallon batch, measure the appropriate amount of salt using the guidelines on the packaging (usually around ½ cup per gallon of water, but this can vary). Slowly add the salt to the water while stirring to help it dissolve. Allow the solution to mix with a pump or powerhead until the salt is fully dissolved, which can take up to 24 hours. Make sure to check the salinity with a hydrometer or refractometer, adjusting as necessary to achieve the specific gravity recommended for your type of aquarium.

The ideal salinity level for an aquarium using Instant Ocean Sea Salt depends on the inhabitants of your tank. For most marine and reef aquariums, a specific gravity of 1.020 to 1.026 is ideal, which corresponds to a salinity of approximately 28 to 35 ppt (parts per thousand). It's important to check the specific needs of your aquarium's inhabitants, as some species may require higher or lower salinity levels.

Instant Ocean Sea Salt is specifically formulated for marine and reef aquariums and is not suitable for freshwater aquarium setups. Adding it to a freshwater aquarium would increase the salinity levels significantly, making the environment uninhabitable for freshwater species. For freshwater aquariums, it’s best to use conditioners and treatments that are specifically designed for freshwater habitats.

The frequency of water changes with Instant Ocean Sea Salt in your marine aquarium can vary based on several factors including tank size, number of inhabitants, and type of filtration system. As a general guideline, it’s recommended to perform 10-20% water changes every 2 to 4 weeks. Regular testing of water parameters can help determine the necessity of water changes more accurately. Always match the temperature and salinity of the new water to your aquarium's conditions to avoid stressing your aquatic life.

  • used for my Opau Ula Hawaiian shrimp
The media could not be loaded. works really well, safer than other alternatives. These shrimp need brackish water so measuring is essential AND be sure to full dissolve before adding any livestock. This salt has a fairly quick dissolve rate. Highly recommend.

  • Good stuff
Size: 160 Gallon
This stuff works just as good as the expensive stuff I used to put in my aquarium. If you can find the right place to buy it it’s not quite half the cost as a expensive stuff, but it works just as well thank you.

  • it seems like salt, it's labeled as ocean salt
I guess it must be ocean salt then. I didn't lab test it but it certainly is salt of some kind according to my salinity meter. I needed it for healing tanks and the red clawed crab that likes brackish water. It is ground finely so it dissolves easy which is great. So far, none of the pets disagree with it so take it for what it's worth. This wasn't the most expensive one but considering I needed much less and it is salt from the ocean...it's kinda pricey in general. Some aquarium hobbyists say you can just use kosher salt for a fraction of the price but "ocean" salt is supposed to be more beneficial for the aquatics. ... show more

  • For fish only, not coral
Size: 50 Gallon
My corals have not grown much at all with this salt. Definitely use reef crystals even if you only have a small amount of soft corals in your tank. I thought it wouldn't matter but it does.
