I've got a 3 chamber sump with a center return that my fuge feeds into. I purchased some sugar fine sand that I want to use to create a dsb in the fuge. How well does the sugar fine stuff need to be rinsed? Ive never used it before so i dont know what to expect. I was planning on rinsing it and then taking the fuge offline for a couple days while whatever's left settles before turning it back on. Any suggestions are appreciated as im trying not to create a dust cloud for all the livestock. Thanks.
