I am going to add 2 reactors to my sump. I want to run carbon and bio pellets. This is going in to a 150 gallon tank with a 40 gallon sump. Any suggestions on what size and type of reactor I should get? I'm a most bang for my buck type so I just need something that is cost efficient and works well. Also any suggestions on the brand of media I should use? Any advice would be much appreciated. Thanks guys.
