it is amazing how defensive this thread has become: those for and those against...
it almost seems like a battle between coke and pepsi drinkers...sorta kinda...
here is my reason for not using oceanic...
ahem...i ca not reveal the people i spoke with about this as for him to not lose his job...
standing around a lfs one day...ah, yes, it was bright and sunny...well, it is southern california and it is mostly sunny everyday 9except earlier this year!)...
i was sick and tired of the nsw we get here...catalina...for the past several months, i was getting this weird slimy algae i have never seen before...let's call it mother natures batch inconsistency...
so, here i am, standing around and i talk to one of the more knowledgeable employee's (who will remain nameless). i asked which artificial salt is good. this employee replies without hesitation 'tropic marin'. i say that i don't see it in the store. the employee says that it is not carried here. he/she purchases it elsewhere. i asked what do they sell here. this person mentions 'oceanic'. i asked why doesn't he/she use it on their personal tank. this person replies 'because i have seen and heard catastrophic problems with it'.
also, after reading anthony calfo's forum and the fact that he doesnt like oceanic's formulation from the get go...really, i may read a ton of articles, journals etc...but i am not directly involved with reef aquaria science. i would rather trust the opinion of someone in the field. when someone reports that they are having horrific problems with something and someone else refutes it by saying that 'they' never had a problem is extremely unscientific on both ends.
i do not have the time...nor the financial means to 'experiment' with things as criticial as salt mixes. i am not going to blow thousands of dollars worth of organisms (not to mention the extinguishing of life) because i will not be open to differing opinions.
as honore balzac wrote in pere goriot by the character, Vautrin said 'only a fool does not change his opinion'. i will honestly say that i have been a fool many a times! and i try to learn from these.
besides calfo's statements, there are just too many ancedotal threads about problems with oceanic. maybe they are just rumors and these individuals want someone or something to blame for problems...but i do not hear stories of tropic marin or instant ocean horror threads.
