Large (dream?!?)tank brainstorming thread, input appreciated!

[WarDog]

Unless your crawlspace is close to 5' high, you are going to get tired of that real fast. Especially if you plan on having a sump down there. I like to joke that they are only good for Hobbits.
You could however, plumb a drain from the tank stand, through the crawl and into one of your house drains. Makes for easy water dumps.

Sounds interesting, following along!
