Sump size

[alton]

Alton....I like your list.

What's the purpose of the powerhead in #2? I thought about it for a minute but did not come to any conclusions. lol And, any reasons you wouldn't combine #2 and #3?

Just curious because I've been thinking about our sump design for our 220g that we are working on.

Also....I love #5 because when an auto top-off is not being used or if it fails, it's so annoying to have to top-off every day. I'm doing that right now. People so frequently cut the last section (return pump section) short.

I got the idea at LMAR. One of the speakers whose name I can not remember spoke on sand only fuges.
