Ok... so now that I've decided to go with the ATB 840 (thanks Mojo!) I have a few questions:
I don't see a gate valve on the skimmer, does it have a wedge pipe? Do you recommend putting a gate valve on?
Also do you recommend upgrading the impellar to the purple? Can the WM Red Demon be used w/ the ATB 840? I like to keep a decent amount of water in my sump and I prefer not to raise the skimmer up on a platform. Does this force me to use the stock impellar? I have a fairly light bio-load (180 display / 280+- total w/ a 8" FoxfaceLo and a 7" red sea Sailfin) but may increase it by a few smaller fish.
Thanks again!
Does anyone know if the ATB 840 has or needs a gate valve?
And do you think I need the pinwheel upgrade?
