OK, I have no other pesky questions. All good comments, thanks y'all (I'm in the Carolinas after all, though not a native), appreciate the comments. Various opinions, various preferences, and I'm assuming you've all done/are doing shrimp. Also useful to be reminded air bubbles don't really oxygenate, movement does... and movement can be achieved different ways (hob return, powerhead, air pump). Shawn
