Reef Salt

Start with approximately ½ cup salt to 1 gallon of water. Once mixed with the base amount you can adjust the salinity to your desired level by adding more salt or water.

Always use RO/DI freshwater as you never want to use tap water in your saltwater aquarium. The ideal water temperature for mixing is between 74- and 76-degrees Fahrenheit. You can raise the water temperature after mixing is completed to match your aquarium temperature to avoid fluctuations.

Stir or use a small circulation pump to mix the salt for 15 minutes or until water is clear. 

You can store the mixed saltwater for up to 5 days in a closed container. Due to chance of evaporation test salinity before use. You do not need to circulate the mixed salt during storage but is beneficial to mix briefly before use.

Waterbox Salt is packaged in black bags to protect against light exposure. Opened bags should be securely closed in between uses and stored in a cool place.

Any changes to an aquarium should be made over time to reduce the risk of causing fluctuations to your water parameters which can stress livestock. Our recommended method for switching salt is to do a weekly 10% water change with Waterbox Salt for the first 4-6 weeks and then resume your regular water change percentage and schedule.

Waterbox Sea salt is designed as a more economical option for fish only systems or reef aquariums with only soft corals due to the lower Calcium and Magnesium levels. 

Waterbox Reef salt is designed for mixed reefs, SPS and invertebrates – providing higher Calcium and Magnesium levels which are key building blocks of LPS, SPS and invertebrates. 

You can find the batch number under the lid of the box.

Test kits available to hobbyists are not able to measure changes with 100% accuracy and can sometimes be used incorrectly. Any variation is typically less than 3% and will have no impact on the aquarium inhabitants.
