That's freakin amazing!!! Thanks for sharing!!!

Insane. that one clam in the corner of the outdoor tank is HUGE.

That reminds me of our visit last week to the Vancouver Aquarium. Although admission is expensive, I highly recommend checking it out. They have some huge clams on display. I will upload some pics and link to them later. The BC coast exhibit was also outstanding.

WOW :crazyeye: What a cool set-up. And some of those clams are amazing.

I wonder how they safely control the salinity of that outdoor tank when it rains? Maybe it just doesn't rain enough to cause dilution. Maybe it just rains enough to keep it about right with evaporation...hmmm...

Did you notice the huge surge tank above the reef display?

Interesting, I didn't realize Delbeek left Waikiki this year to go work at the new Steinhart Aquarium. Man, I think I'm totally going there after it opens later this month!!

... I think the rainwater/evaporation isn't a problem for the Waikiki outdoor aquarium because the turnover from natural seawater is probably large enough to compensate. (Their source water is a well which brings in pristine seawater from underground.)

And that surge tank is the granddaddy of them all. Bruce Carlson's legacy :) (hence the term "Carlson surge").

I've never been to the Waikiki aquarium but I'm totally going if I ever make it to Oahu.

WHats the point of a surge tank????

Water is slowly pumped up to a holding tank which is above the main display. When the holding tank hits a certain volume, it rapidly dumps it's contents into the display. This creates a large wave (or surge) and simulates ocean conditions. It is another way to create random flow, as well as a nice way to suspend stuff that may have settled somewhere.

that place is amazing, i went this summer

i gots pics to prove it :biggrin:
