Water motion in tank.

[Troy F]

Shane, I was thinking about what you said about "very little tidal action in the tropics" and would like that clarified if possible. I've not been anywhere tropical myself but do have an understanding about the tidal dynamics and it would seem to me that location would dictate how high the tide would be. I would guess that a lagoonal reef may even get more water motion from tidal action. Did you dive a forereef? I'm a little envious. There is a guy on www.thereeftank.com that just got back from the Indo-Pacific, hopefully he's going to send me a copy of his dive video.
