Water is clear, fish are doing beautiful.

I've used Instant Ocean Reef Crystals for a long time, and everyone in my 700 gallons of salt water has been happy for an equally long time.

I've used Instant Ocean Reef Crystals for a long time, and everyone in my 700 gallons of salt water has been happy for an equally long time. That includes fish, inverts, macro algae, polyps, etc. I'm not a fish, but I think this is the right product for a saltwater aquarist who want to save money without cutting corners on product quality.

The large box comes with the salt split into 4 bags which makes it easy to store. Dissolves quickly. Helps keep parameters in line. Keep mixing for 1 day to stabilize the PH.

This is the only salt mix I use anymore, and I no longer have to add any trace elements. Just keep up with your weekly water changes, and this mix will give your reef everything it needs.

I've tried pretty much all the brands of salt mix over the years in my 210 gal. reef tank, and keep coming back to Reef Crystals since it does what it's supposed to do and the price, I feel, is the best bang for the buck.

Dissolves better than Red Sea (I was using before) and has everything you need in it for a reef tank. No additions are needed if you perform regular water changes.

I've been using this salt for a few months now and have gotten consistently good results. This salt comes packaged in 4 separate bags where each bag is equivalent to a 50 gallon mix. The salt is fairly easy to mix if you intent on stirring quite a bit, I however just stick a spare powerhead in and leave it to mix for a couple hours for consistency and to fully oxygenate the mix but usually it can be done shorter. If when using this salt you don't use an individual 50 gallon bag entirely make sure and squeeze the air out of the bag as the salt will absorb the moisture and readily clump. The Reef Crystals in particular promises to restore magnesium and calcium as well as other trace elements. From testing I cannot say if it has added any trace elements, this is probably due to them being trace elements and are in very small quantities to low to be measured on a hobby test kit so I still supplement regardless. However it does add a fair amount of calcium and magnesium and maintains pH very well in addition to supplementing externally with 2 part and magnesium. I usually do a 15-20% water change every week with RODI water and I use this salt every time. I have fishes, invertebrates and corals ( both lps and sps) and all are doing great using this salt. Overall I would recommend this salt as it is a quality mix and has a great price accompanying it.

Size Name: 50-Gallon Verified Purchase
Great product by far, and very excellent results in coral, and fish seem "happier". Saltwater is supposed to be at 1.024, but on the package it says it makes 25 Gallons of 1.021 salinity level (specific Gravity) reef saltwater. (there are two 25 gallon boxes that make 50) so i was a littl ebummed since i have a 120 gallon tank (i bought 2) and it was spot on with 1.021 salinity level, had to add a little of the normal instant ocean salt. Overall im happy, beautiful results in coral overall, and will purchase again.

Nothing much to say about salt. This is salt. Lots of it. The small crystal size means it dissolves pretty quickly. That also means it clumps together very quickly when humidity is high so make sure to keep in an air tight container once you open it. The salt inside is split into 4 sealed bags, which keeps it fresher if it takes you a while to use this much.
