H2Ocean salt

[Slyguy00]

So I have recently switched over to H2Ocean salt as I have heard lots of good things. My sps seem to love it. But since i have started using it everyday i get this wierd brown slime on my sand. Im wondering if anybody has had this happen from using this salt? And if so is there any way of getting rid of it? Nothing in my tank has changed, perameters are all where they should be and iv even reduced lighting and still no success. Any info would be appreciated
