That price ain't gonna have RC parameters, I did the swap and didn't realize how low Aqua forest sea salt params is. Ended up basically crashing my sps cube (my fault). Also the bags are notorious for not sealing properly, so keep some IO buckets around for storage.
If your going to bump up the numbers alk, cal, mag to what you want it's a good deal, mixes quick and clean IME. But again, it's not a "reef" salt.
I run 2/3 Aqua forest to 1/3 reef crystals when I mix currently to boost numbers.
