Well I think my number one focus is going to be letting my reef decide which brand of salt is best. Sure there's lot's to debate here, and some serious concerns have been brought to reefers attention, and some really good points have been made here too. I have used the same brand of salt for over five years now without any problems. I have had minimal to almost no algae in my reef, all my fish/corals/inverts have lived long and healthy, and my water perameters have always remained stable.
I'm going to try another salt mix for the next few months. After that trial period is over, I will then let my reef decide weather or not I should stick with the other brand. I'm more concerned how my fish/coral/inverts react rather than if someone states that the numbers don't jive. This may be an old school way of thinking but it's what works for me, or should I say my reef. I am very sceptical about using this other brand, however if the reef reacts in positive ways, then who knows-maybe it's a step in the right direction.
cheers, the salt wagon jumper
