Reef Crystals = very high alk?

[ReefCube]

I just started using this stuff about a month now noticed some corals loosing color and bleaching. tested out the water and noticed my alk is 15 dkh right out of the bucket! I tested it 2 times wondering is anyone has this problem? I might have a bad batch?:confused:

I had the same problem when i added salt to my bucket before water but now no problems you maybe had a bad batch :(

i never had any problems with reef crystals. of course i never tested for anything ran a skimmer or any of the other supposed needs. and i had amazing growth and color with it. maybe you do have a bad batch but i know from experience i didnt have problems

Typically it should test at 12dKH @ 35ppt.
