LF large tank for sump
 

I am in the process of putting together a 630 gallon tank and I need a sump, if anyone has a beat up large tank. or know something that will work good shoot me a line.

A cheap alternative if space permits is to use a water trough. I know a couple of guys using them and they are very happy with them.
here's an example; http://www.smartpakequine.com/Produc...m-_-NA-_-18031

hmm that would probably work well. now would you even bother putting baffles in that or would you set it up different so you don't get micro bubbles?
