What is your dream tank ?

[TikiDan]

I would build my house next to the ocean and incorporate an indoor olympic size swiming pool being continuoslly feed NSW that is filtered and heated before being added. The tank would have view panels on 3 sides connected to my entertainment room, kitchen and bedroom. No need for skimmer due to constant supply of fresh sea water.

Surge would be the quick removal of water from the main tank, and then dump new water from a holding tank. That should take care of water movement, and water changes. Like tom says... Go big, or go home
