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!

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?

Order by itself.

Make sure you order this product on a seperate order. They shipped this along with other items like a glass heater, hydrometer etc etc all in the same box. All items were not in good shape on arrival. However Chewy made it right. Just a heads up.

Good value with limits

I am trying to be advanced aquarist with stony coral. They are growing in this salt. It has high alkalinity so I never do more than 5 or 10% water change. ICP tests using this salt show Lithium and Baroum slightly elevated with no immediate concern but only way to reduce these is with expensive imported German brands.

looks half full

ive used reef crystals in the past and it works well. i just got another bucket from chewy but it looks half full. im going to have to get a scale to weigh it. looking thru the bucket it looks less than half full. not sure why you would use a 5 gallon bucket for 2.5 gal of salt?

Dirty salt and bucket

The bucket came not boxed and the bucket was nasty dirty. If you take salt out you get dirt all through the salt

Reef Crustal salt

Much better than the regular Instant Ocean. Was using IO for years and switched to the IO Reef Crystal and it mixes so much faster and cleaner.

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.
