i just finished reading a massive thread on the other board, about hobbiest's that switched to crystal seas salt. its very sad most of the results are very negative. i haven't heard many reefer's horror stories here on this site. i am so glad i listened to some of the old salts on this board, (who seemed to be in the majority) and kept using my metal tainted instant ocean. this kind of lesson is very valuable. it will keep me from ever making a sudden change on my tank because someone makes an unsubstantiated claim. are there any good or bad results from anyone on this side of the fence?
