Bio Balls. Whats the deal?
All I read over and over and over again is how horrible bio balls are and that they are nitrate heaven. But bio balls are just surface area for bacteria to grow on am I correct? Doesnt LR do the same thing? My reason for asking is that it would be easier for me to put bio balls in my sump rather than lr. So whats up with the bad rep. Is there something Im missing lol
