Thanks everybody, got busy with school for awhile and forgot to check back in lol. I mixed some up yesterday and I have to say, the way it dissolves is far superior to the salt I have been using (IO). I am changing because with IO I always have to buffer for ph. I bought 50 gallons worth of salt and if it goes well I will be buying more. As far of the expensive part, I did the math...if you compare 160 g bucket of IO to a 200 g bucket of Tropic Marin at LA or premium aquatics I think it is, it really isn't that much more. When you add in expenses of adding in calcium and buffering the water, it is actually cheaper to get the better salt. Assuming the it is truely as balanced as it says it is.
