does your aquarium need a boost in calcium (proportianal to alkalinity)? If so, you probably made a good choice.
Many people mix IO and Oceanic salts into a 'custom blend' and have had good results- I'm one of them.
There's no well known record of problems when switching between IO and Oceanic.
thanks, and yeah my alk was 13.01 and my calcium was only 370 so i needed to boost it a little to get where i needed to be so i figured the switch would help but i have always used IO salt so i was a little worried about the switch..
