Thanks for the replies. I really appreciate the offers!
Here's a little bit more information about my setup. My display is 350 gal, refugium is 50 and sump is 40. I live in Foster City.
I don't mind driving out of my "area", but was hoping it could be for a large amount to make it a time / cost effective trip.
Again, I really do appreciate the offers but I'll need a pretty big amount to help with filtering.
Thanks,
Kevin
