Post subject:  Grow bed for Biological filter

I am building a mini version of the indy 23 with one 275 gallon fish tank and I am trying to decide what you use for a biological filter. I was thinking of using a media bed or a media tower or a dedicated biofilter. I am leaning towards a bed or tower since it gives me more growing space. Are there any draw backs? I noticed that some people seem to separate their towers and media beds from the main flow of their system.

I am also thinking of what to use for a mineralization tank. I notice some people use brushes but I was thinking about using this material. https://www.theaquaponicsource.com/shop ... 16fd43adaa. An cutting it up into sections to make a series of removable blades placed into a tank. The water flow would start lower in the tank and then I imagine as they get clogged the water would rise in the tank to give me time between changes. I would build in a overflow just in case.

Thoughts?
