I couldn't find that post but bio balls are great for nitrite conversion but not for nitrates, you need something else like macro algae or bacteria and carbon dosing to take care of that unless you use water changes. I'm not a fan of carbon dosing it works but it strips the water too quickly. I prefer macro algae, I'm currently using chaeto but I'm really considering going back to caluerpa.
