had same problem in sand bed. tried red slime remover, worked but came back within months. tried rhowa phos w reactor, helped alot, but still never gone. tried more flow, nope. new bulbs,nope. cut back lighting,nope, cut back feedings, rinsed food,nope.finally w bb and havent seen for almost 2 months. good luck, sometimes wonder if sand bed gets to old, stirred my shallow sand bed weekly to no avail.
