Fish Crazy
<SNIP>Your not "down" on flow at all. In the manual the filter circulation rating is 607 GPH. Your not doing bad at all.
Hagen got back to me, repeated what you have said. I double checked the manual and your both right. It states an actual flow rate of 2300 lpm.
It just seems less than when it was new. I wish I had bench marked it when it was new.
I'm happy now I know the facts.
