[QUOTE=LVMAS;24248276]I know this is an old thread but I have been using Marine Environment Salts (Aqua Craft) for about 20 years. Its worth the extra money to me. I have tried other salts. I always go back to Marine Environment. You must to give it 24 hours to dissolve before using it. That's the closest thing to a negative comment I have for the Salt. I have not used the other Aqua Craft salt mixes.

I have no opinion of the "S-15 Report". It was not a consideration....
