Consistent!
I’ve used Instant Ocean Reef Crystals for a long time, and it continues to deliver great results. The mix dissolves quickly, produces clear water, and holds stable parameters — calcium, alkalinity, and magnesium are always right where they should be. I mix mine in a 32-gallon Brute can with a heater and small pump, and it’s usually ready to use in under an hour. No residue on the heater or pump and no cloudy water. Corals have good color and polyp extension, and I’ve had excellent growth over time. Pro tip: always pour the salt into the water (not the other way around) and use a powerhead for even mixing — it keeps it from clumping and helps the parameters stay consistent. I’ve tried a few other brands, but Reef Crystals gives the best balance of quality and cost. Perfect for routine water changes and dependable results.

Easy to use, reliable product
Works as it should. I've been using this brand since I started my saltwater tank. My second bucket came kinda chipped up, but all the salt was intact and uncontaminated so no complaints. I will continue to order because this is a good deal.

Great product great price free delivery
The price is less than my local fish store.But most importantly free delivery. I've been using Instant Ocean Reef Crystals for my reef aquarium for years and have had nothing but success

It's the industries most popular salt for a reason.
I have been keeping Reef Aquariums for over 30 years, from the days when reefers salivated at what Julian Sprung would write his next magazine article. Instant Ocean is IMHO not the industry standard, there are certainly better salt mixtures you can buy but at the end of the day it will make very little difference as Instant Ocean is certainly good enough to keep any coral I have come across alive and thriving. I don't know why one guy is saying go to BRS for the salt. BRS is selling this for $63 while Amazon has it for $44 with free shipping if you have Prime. The reason this salt is the most popular is that it gives the greatest bang for the buck and while its one of the cheapest salts its still a very good salt. I am not a fan of some of the latest pharmaceutical grade multi mixture salts that require like five different things to be added in exact proportions to make a perfect batch of salt. It's too complicated and just an accident waiting to happen. I am a Fan of Red Sea Salt but at almost double the price per gallon of water and not seeing any difference in coral growth I went back slowly to instant Ocean. My tip to you is that when you make a mix of lets say 50 gallons of water you make sure to let it mix via the pumps for at least 24 hours and aerate it properly. Do not add salt all the way to 1.026ppm as the salinity will increase as the mix goes through the 24 hour cycle. I usually stop at 1.020ppm and then check it again in 12 hours and add more salt if needed. When that's done test the water for ALK, Calk and of course the temperature. Heat or Cool the batch to the temp of your tank and then test the Alk, Calk and Mg. If any of them are down from your aquariums parameters then add the needed components in small amounts until you get it as close to your tank water as possible. Typically with Instant Ocean I rarely have to add anything but sometimes it will be a bit low on the calcium side. Nothing earth shattering but just enough that I would feel better correcting it.

We love bulk!
This is the perfect batch of you have a larger tank or just like to stock up. Personally I just like to stock up so I grabbed one of these and now I'm worry free for a while. No one likes to have anxiety with their aquarium and this takes some of that away.

Excellent product. Worth the price!
This is the best aquarium salt mix on the market (for the price!). It isn't cheap, but this mix does its job a lot better than Marine Crystals. I can't speak for some of the premium brands that cost double what this does, but I can't imagine that they would be worthwhile investments. My reef tank appreciates the quality of the water, and I've had no issues getting the salt to dissolve by hand in just a few seconds.

Get the bucket not the box
Good quality salt bucket, I always use the bucket over the box, I had several bad salt boxes over the years but never a bad salt bucket.

Great salt for stable parameters and value
Great price for $65.00 with free shipping. Have been using Reef Crystals for about eight months now without any problems... creates good stable parameters for a reef aquarium stocked with softies, SPS, and LPS. Previously was using DD H2Ocean - but I recommend Reef Crystals as it is better value and does a better job IMO
