Is reef crystal safe for salt water fish's
Answer by ChewyNov 19, 2018
While the product is fish safe, never mix salt in an aquarium containing animals. In new aquariums, transfer animals to the aquarium after salt is completely mixed and aerated and specific gravity has been adjusted.

Does this product have all the required additives and supplements?
Answer by ChewyNov 25, 2019
This product contains essential ocean reef elements in concentrations greater than those found in natural seawater with extra calcium to encourage the growth of large and small polyp stony corals as well as coralline algae. This salt provides vital nutrients and extra vitamins help to promote vigorous growth and survival of corals, anemones and other invertebrates.

How much alkalinity does reef crystals have? My alkalinity is super high after using this!
Answer by ChewyFeb 23, 2021
The alkalinity is between 3.5 and 4.5 mE q/L for Reef Crystals.

How often do you have to put the salt in the water? And how much for each tank size?
Answer by ChewySep 29, 2021
To prepare small quantities, use 1/2 cup of Reef Crystals per each U.S. gallon of water. Every 1.4 lbs of Reef Crystals is formulated to create 5 gallons of saltwater at a specific gravity of 1.021. For more detailed instructions, please click on the attached photo.
