WTB Canister filter suitable for 180 gallon - Edmonton

[raoul duke]

As the title states, I have graduated from my 60 gallon freshwater tank and bought a 180. I am anxious to get all the kit together to get it up and running but like most people I am on a budget and need to buy all the stuff over time and second hand where possible. Not sure if it's better to get a filter rated up to 180 or two smaller ones, but if anyone has something suitable for sale I'd appreciate a PM about it.

P.S. I thought I'd try a WTB add after accidentily posting on some really old WTS threads. My bad, not very IT savvy!
