I think IO is great. I normally use it. I bought some Seachem Reef Salt just recently b/c my LFS was out of the 90 gallon buckets of IO. Big mistake, the stuff does not mix well, especially in cold water (Which my RO water is before I heat it up). I am probably going to trash the rest of the bucket of reef salt and go get some IO. IO has been around for ever, and it is proven stuff. Plus they use it for all of the tanks at the GA aquarium here in Atlanta. |
