I am just trying to see what should I use :

Arm Calcium Reactor Media Fine
Arm Calcium Reactor Media Course

or anything other name brand please let me know
 
Mushy sucks. Go with the course media, ARM is good stuff.
 
mushy will restrict the flow as well as collect more detris...with the flow restricted you will be constantly adjusting the bubble count and effluent rate to dial it in again.
 
Extra coarse and use coarse and dolomite in effluent reactor help raise ph leaving reactor and get great flow and results with extra coarse used coarse before like the rocks now
