I use reef crystals, although I'm plannning on switching to Oceanic. I used to get the dreaded "brown scum". Very simply, I vigorously stirred and stirred the salt mixture as soon as I made it and the problem went away and never came back. I thought that just putting a powerhead in for a day or 2 would mix the salt in, but it needed seperate agitation to thoroughly mix with my RO/DI water. Try it, you'll like it.
