Hi all, I got seagel to replace my bioballs in my 29g cube and purigen and have a few questions. Where does the seagel go in the tank? I have it at the bottom of the middle chamber against the slitted wall that leads to the pump. Also, I wasnt sure at all where to put the purigen so I put it ontop of the biocube charcoal filter in the middle chamber. The water is running right over the purigen pack but I dont know if this is correct. I really need a media basket to hold the purigen, seagel, and charcoal filter cartridge but as of right now where should i place these items? All comments are greatly appreciated!
