LFS use these systems because they are easy and effective and they generally don't have livestock in these systems long term
in a home system your animals are there for life and especially if it is a reef or mixed reef these built up nitrates can cause problems.
we must remove nitrates from our systems faster than it is created. bioballs being removed is just a faster means to that end, they can be used but better not to
bottom line is for nitrate production, bioballs work too well
if you have the means to remove nitrates faster or more efficiently than they are being produced then bioballs are fine

THANK YOU SO MUCH!!!! thats all i was asking. everyone was trying to ask. Im getting the tank started this weekend and i didnt know if i should have keeped the bio balls or not. LFS were telling me to keep them but your reply makes sense why they use them..
