bioballs huh... I am thinking I am going to stuff some bioballs in the bottom part of the overflow and then put the sponge thing housing my biomax on top of that, probably sticking out a little more than stock that way it prevents fry from going through the slits and hanging out up there - it is kinda funny they are interested in swimming in there especially if I am messing around with it because these endlers are so curious - but I don't want to hurt or trap any of them
