Hi Greg, yes I did and it did indeed kick back the slime. There are still some spots but nowhere near as bad.

This problem with the frags is I think something else. I guess it could be that the weekly water changes caught up to me and the new seawater has params out of whack. I had to buy a huge box of Mg supplement from littlesilvermax and I've already used about about 20% of it just correcting my tanks (and I'm not there yet - I'm only raising the tanks by 50ppm per day, they should be hitting their target values tomorrow or Thursday) and my water change water.

So much for Aquamedic salt! Problem is I'm so stubborn. I paid $90 for this bucket of salt, I can't throw it out. Hopefully it's just the Mg is out but I guess I should double-check the Ca and Alk. At least Ca and Alk don't appear to be deviating in the tanks so I don't really suspect that those params are out. Nevertheless the Mg of 900 is way too low, I won't be using or recommending this brand of salt to anyone. If it's a case of it's a just bad batch, Ok fine, but the thing is, they advertise that the levels are a certain thing, so you expect it to be what it claims it is. A bad batch means there are quality assurance issues, and thus I'm still concluding that I won't use or recommend that brand again.

Anyhow so I have to wonder if the latest casualties are a result of the chemistry of trying to raise Mg over such a profound range. And of course there's the potassium thing too.

Next salt for me is Reefer's Best..
