I use Marine Environment salt...only available at Aquarium Illusions. I used IO for the first 15 months in my tank but I could never get control of my numbers and the salt just never disolved clean. After looking at a lot of other forums, like RC and RL and RAG, I found that most of those people swore by ME. Since making the change, I have to say, it's awesome stuff! A little more expensive but given what kind of dough we spend on this hobby, cheap salt seemed like a mistake.
Just my 2 cents.
