i use mortons salt makes food taste better, oh wait wrong salt.

i currently use reef crystals, used reg instant ocean before, growth is better and parms are better but no real big diff(except price). i switched to sps while using reef crystals and all is happy in my tank. thinking of going to tropic marin bio actiff, but ive read some posts on RC from people in europe, which is where tropic marin is like our instant ocean and they would rather use instant ocean over tropic marin, so i dont know what the hype is.
