i have two fluval 305 filters one contains just bio max and the other i have bio max and carbon and amonia remover. the tank houses my arowana. i was just wondering if anyone uses other types of media which are better. thanx
Ya im tryn to convert my brother over to regular water changes but he uses carbon and ammonia remover and does a WC about twice a year LOL. Your arow will be very happy with a 50% weekly and the space used for bio would be good. I have heard alot of good things about the EHEIM EHFISUBSTRAT PRO as well
