Whats a good type of biopellet to use? Im using Tropic Marin currently, but I'm having an awful time getting them to tumble. I went all the way up to a 600 gph pump and it barely moved them. I went and returned the pump and got the new sicce bio pellet reactor, thinking there was possibly something wrong with my old one and it's the exact same thing. My only conclusion is, it has to be the pellets.
