TGW1- are you sure its media? The stuff that is in the filter bags where the water goes thru it(generally can't see it) is just carbon(?) and does nothing more than make the water clear. Doesn't help with ammonia like real media. At least that's the way I understand it.
My personal experience is don't be to much of a clean freak when it comes to the tilapia. The glass sides will hold some of the good "bugs". At most, I will wipe clean the glass in half the tank at a time.
FNC, I asked the fish person @ Petsmart about the media and he explained that media was in the bio wheel also said it was in the filter, but I don't think these reps are expert but he said his aquarium was set up this way. I don't know ??

Those bio-wheels work pretty good. Once those kick in, you would be shocked at how many fish they will support feeding moderately.
I have (2) Marineland 350's and one 400. I just started the two 350's with the other media last week, killing two birds with one stone.
