Spots where the sand compacts itself and it can hold in all kinds of bad stuff unlike gravel it can't "breath" and let water flow through it letting the bacteria to be broken down
I've had this problem before and when I disturbed a couple spots alot of nasty shT came out and the lvls of everything sky rocketed. Maybe it was just me but I dislike silica alot
