I shall not name names here, and neither do I claim to be an expert.
Anyway, for filtration there are 3 basic types. Mechanical, biological and chemical (in the following order). Of course there are others such as cryptic but I won't be discussing about it here.
It is a common belief that bioballs, ceramic rings are nitrate factories. True, but to an extent. A good filtration system will employ all 3 types. If you can get your mechanical filtration dialed in correctly, there would not be an issue with the biological stage, which in your case is your bioballs. Now, to simply remove all your bioballs would mean that you lose most of your biological filtration. Its a drastic and unpractical (even you commented where all your bacteria will grow).
