Wouldn't it be safer if we live in a closet and only eat intraveniously.
With live rock and a deep sand bed you with have neither high ammonia nor high nitrate levels. If you have bioballs you will not have high ammonia levels, you may or may not have high nitrates. It seems to me to be safer not to have the bioballs.
