thanks for all the replys i was thinking of switching to instant ocean ,i'm using coralife salt right now but i don't it find except at petsmart and only in a bucket ,even though thats what i buy ,i need to use something thats more readily available ,like instant ocean ,or reef crystals ,i can order coralife at the lfs but a bucket would cost me 56.00 compared to 50.00 at petsmart , instant ocean is only 41.00 for a bucket at another petplace i pass during the day. so i'll save a couple bucks and i can get it anywhere ,and i won't have to buy a bucket all the time.
