Hello friends, last week I purchased 40 lbs of live rock from an established tank, placed in mine with yellow tang. My pure white sand, has now turned solid brown !!! Research states diatom. It's everywhere in tank. Other then water changes, what can I do to alleviate this problem ? I've done 10% water change twice, only to get worse. Tang is swimming actively so far. But brown sand looks horrid !!! Also protein skimmer is yanking nasty content. First major issue, I've had in 2.5 yrs. Never experienced this problem in my 20 gal.
Thanx for any assistance
