Hey all, just looking at filtration ideas and I've seen some posting about Poly-Fill. I was curious if that can replace the filter floss on top of my intank media basket or if it should only be used for bio load? I'm running Filter floss, carbon, bio max right now in chamber 1 basket and was looking at doing Poly-Fill, Chemipure blue, Bio max. I'm also looking into Green machine uv or Coral life uv but not sure how to place/fit it. I have Neo- Therm 75 heater in chamber 2 and Sicce .5 pump in chamber 3
