Hey guys i think i read somewhere that you guys recommend replacing bio-balls with LR in our filters? Whats the purpose of doing so? I currently have a 75 gal wet-dry so can i just crush up some LR and replace them with bio-balls or do i have to keep them submerged in water all the time? Thanks alot guys....
