Questions & Answers

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 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.

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.

Awesome delivery

The service and packaging from chewy.com was awesome. The 200 gallon salt box came fully intact and on time. Would definitely reccomend chewy and will purchase in the future. I also setup the automatic delivery just be careful of price it varies wildly.

about shipping and handling

i purchased bucket salt and some carbon last month in January. and they deliver on 1/20/2022. the bad thing is the deliver guy just tossed my order over the gate onto my driveway. when i open the box, one bucket of salt busted open and i salt all over the box with the carbon. beside that, everything is good and i will continue to shop chewy if i need anything . thank you for the good service and hope next time just put handle with care sticker on the box to prevent same situation happen again in the future.

Good salt for half the cost!!

I would buy high end salt.. wanted to make a change, slowly been adding this salt to a mix of the old salt I used, corals seem to love it.. half the price of the competitors of high end salts. Have nothing bad to say about it
