IO Salt Question

[kien]

Have you tested the new batch of IO saltwater to see how much alk, calc and mag it is giving you before adding that stuff? It could be that your current IO batch already has high(ish) levels of those chems and now you're trying to mix in more! Just a thought. Those levels can vary wildly from bucket to bucket, even with the expensive salts. I make it a habit to always test those levels with every new bucket before I dose anything.

My IO mixes do tend to to leave a tan residue in the mixing bucket. I always assumed that was normal :-). Hasn't seemed to affect anything for the 5 ish years I've been using it now.
