diatoms/cayno
every new tank see's this faze
water changes and water flow are your friend with this type of algae
and a nice turkey baster to blow off rocks and sand if need be
I've been through this, just like everyone else. If you want to take the natural route, do nothing. If you're impatient and want it gone NOW, just like me, use Kent's marine tank clarifier. And for your sand, I found that a goby would your best friend. I can't stress how clean the sand looks of there is a goby in the tank. My only problem is that they kick up some sand in the tank and if you have a good current going, it takes some time for it to settle.
Love my diamond goby and I put some sand sifting star fish in too now my rocks and sand look great and my 90 gallon has only been up and running for like 2 months...
More frequent water changes.. Try to get a bigger clean up crew. Goby is definitely the way to go for the sand. What are your water parameters lateley? How often do you feed?
I wouldn't add any chemicals to the tank. Water changes/upping nutrient export, and cutting back on feeding would be what I would suggest. I would not add another fish to the bio load to correct this problem either.
