IMO instant ocean is ok for FO tank,but if you are considering reef i would consider another type or brank of salt.I curently switched to Tropic marine reef pro and very happy with it.You will find many and i mean many opinons on this topic.
I just started seein the Tropic Marine at ***** and it is the cheapest salt I have seen for sale. 50 gallons worth for the same price as 25 gallons worth of Oceanic which I am currently useing but don't have enough experiance to begin to compare. Im curious to see what people think about the two as far as comparisons go!
I've tried both Instant Ocean and Oceanic salts...I've noticed that with IO, my tank very blantantly breaks out with green hair algea...With Oceanic, my calcium goes up quite a bit. I'm thinking of mixing the 2 to see what might happen...don't know yet though. I would want to come up with a good ratio between the 2.
I used IO for over a year with no problems other than I was always fighting trying to keep my calcium levels up. I have since switched to Tropic Marin for the last 4 water changes. I've noticed that the levels are a lot better. I also have heard good things about the IO reef crystals. But like mentioned in an earlier post if it's FOWLR I think the IO would be Ok. Do a search on this site, there really has been a lot of discussion about this topic.
I use IO only b/c i bought it when i was a beginner...I plan on switching to reef crystals...though I havent really had problems with IO...dont know if thats the reason why i have alot of cynobacteria?
I keep all reef tanks and I have yet to have any problem with I/O, orther than one bag that was old but IO replaced it and it was easy enough to add supplemental calcium to makeup fopr the precipatated cal etc that was lost. Until I have a issue with it, its still the cheapest salt in this area and works just fine.

Any salt brand will give you green coraline.
I don't use IO, but I do use reef crystals, which is made by the same company as IO but formulated more for a reef tank. Never had a problem with it.
