i think on my personal opinion that in the range of this price of salt this one is the best i also like oceanic because u can prepare it fast but reef crystal have better results for me, 0 phosphates and i like to buy the one of 200 gals instead of 160 to save some money

I was told about this. I bought a box, gave it a try, and have stuck with it every since.
The only draw back is it does not dissolve as described, but I also mix it at least 5 - 7 days ahead of time so that's not an issue.
Buy the box, it comes with 3 bags... the bucket does get hard to open after awhile.. I always had to get someone to open it for me!

Been using the reef crystals for years and wished i would of smartened up a long time ago and switched salt mixes. It never really dissolved as quickly as it claimed and there was always residual salt left in the bucket. Very cloudy even after sitting for a while, and would leave the tank cloudy for about a day after water change. I guess this salt is ok in a pinch, but would rather use a better quality salt mix. Corals not only look better now that i switched from reef crystals but look healthier as well.

My go-to salt By Albert on 6/29/2014

What can I say? This salt dissolves fast, and is incredibly affordable. The parameters of the mixed saltwater is also in line with what I need to keep my corals healthy. Sure there are a lot of other great salt out there, but for the price I would highly recommend reef crystals!
Possibly Bad Batch IO By Jim on 6/27/2014
Jim wouldn't recommend this product to a friend
I've used IO for many years and have not felt the need for the overpriced boutique salts. I bought two 200g boxes for a new tank build. This batch seems to be severely lacking in CA and it does not come close to its claim of "When dissolved in pure water to a specific gravity of 1.026, Instant Ocean® should provide a solution that has 400 mg/L calcium ion and 1320 mg/L magnesium ion." I tested Ca and KH, at 1.024, and while KH is 10.5 Ca is so low its off the Red Sea chart at ~150. The lowest they go is .58/290. That test was verified and after adding 4 tsp of Turbo Calcium levels measured 400 the next day. I should also add that the levels are probably lower being I had a calcium reactor online several days prior to testing.

I find the box easier to handle and the 50 gallon bags reduces clumping. Having it delivered to my front door makes my life easier!

Reef Crystals are pretty much the standard in reef keeping. It dissolves fast and is well formulated. Highly recommended to anyone!

I have been using Reef Crystals for 6+ Years for all my Reef Tanks. I have tried several other salts but I always come back to Reef Crystals. It is by far the best Salt on the Market.
