Naso,
It's not the salt. New tank syndrome. Are you using RO/DI?

I had been using ReefCrystals on my 120. I recently set up a 360, to share the same sump. (increased water volume) Anyway, when filling the 360 I needed ALOT of salt. So, I went with Corallife. In the new tank I put "homemade" LR in it. (concrete and crushed oyster shell....and yes I let it cure for 8 weeks doing water changes weekly) After about a week a brown "dust" algae appeared on the rock and sand (SouthDown). It could easily be blown off with a PH, but would return. It never appeard in the 120 at all! I was told that it was the salt, but don't buy that story. Any ideas?</strong><hr></blockquote>
