carbon reactor

Ive been running mine less the 1/8 the way full.. Seems to start out like it is to much then the next day it settles down and seems to run just about right.. I really dont know how much is recommended and have found carbon in my tank recently... Im running a maxi jet 1200 on mine. Hope this helps

 

I use the reef calculator on the BRS website...I love BRS

+1 on BRS, I run mine nearly full. It does not need to tumble like Bio Pellets do.

 

I use a too little fish reactor almost full of carbon and into another with gfo on a maxi jet 600 the slower the better u want lots of contact just remember to change it ,im not sure about others but i run cheep carbon bigger
pieces they dont break down in the flow as much ,and ive been told carbon is only good for a few days anyway ,change mine 6 to 8 weeks but to each there own,
