Fuge Flow

[Madreefer]

I have a 20G fuge with a Rio600 at one end and a MJ1200 at the other side keeping some gracilia (cant spell it) tumbling. There is two piles of live rock rubble for pods. I don't see any pods anymore, could this be too much flow? I still see my mandarin picking at the rocks constantly in my display and he is fat. Just concerned 'cause I no longer see pods in fuge. Noticed this change when I added the Rio in and removed caulepra.
