WTT 250 gallon setup for smaller set up

[fallin49er]

I have a 250 gallon tank 54 long x 36 wide x 30 high. It has a sump 41 gallons (30x20x16) and is driven by a mag 24 pump. I also have 2 rena xp 4 canisters plumbed into it. This tank used to be a salt water setup but I am using it as a freshwater tank right now. I want to down size to a 180, 150, or maybe a 125 if it is real nice. Let me know what you got or if you are intersted. Might do cash or partial if the deal is right but really just looking for a smaller setup I can move into the house. Thanks.
