Rated 4 out of 5 by Ellery Long time User but have questions about sediments
I have used IO and Reef Crystals for over 25 years in the hobby but not till recently I've been mixing full bags of salt at a time in a 100 gallon food grade water barrel and noticed that there are alot of brown sediment that end up settling after mixing. What is this stuff since it's definitely not seen in my RO water tank?

Rated 5 out of 5 by Steve81 Excellent Product!!
Use this in both my 26 gallon bf as well as my 75 gallon bf and in my experience this salt is awesome. As long as you follow the instructions and use a refractometer and not a hydrometer it is great!!

Rated 1 out of 5 by DaAznGuy Poor Results
I've been a long user of Instant Ocean, I figured since I had good results with it I would give the Reef Crystals a try since my system was much more heavily stocked with SPS.
After using several batches I noticed my Calcium and Magnesium dropping after water changes. So I began testing every salt mix after that. On three consecutive batches my calcium ranged from 300-350 and Magnesium ranged from 900-1000. Very poor parameters. It's lower than what I got from Instant Ocean which is cheaper too.

Rated 5 out of 5 by Marlin Works great for my 65 gallon reef tank!
Just make sure to close the bucket completely after you are done using it, the salt pulls moisture out of the air and it will get chunky if the lid is left on the bucket.
