So you want to know total turnover rate, right?
I was always under the impression that "turn over" was used to describe the flow thru your sump.
And "flow rate" was to describe the amount in the display.
I hope that that guy is wrong.
My only question is the center of these quakes suppose to be near where these 'beachings' and 'weird fish events' happen?
Because he mentioned SoCal had an event. So it should be located down there, right?
Welcome John.
Sounds like you are way ahead of the average "newbie" and your plans look great!
Two things:
1- can your "cheap" light you got with the tank work for your light on the refugium?
2- Glad you found the club. Hope you can make a meeting soon. Next one is March 27th.
