I've found a 125 gallon setup that includes everything (tank, hood, lights, stand, canister filter, gravel, and I think two 200 watt heaters) and was wondering if this is a good deal?
I personally would buy it depending on the condition it is in. Also depends on what kind of canister but i would buy it if it is in good coniditon with a nice stand.
I say it depends on what kind of equipment it comes with, if it's cheapish stuff I wouldn't pay that much. It also depends on your local area, that GREATLY affects used tank pricing.
SoCal stuff is typically cheaper than average and places like Alaska are higher than average, not sure how it is around you.
Just make sure everything works and the tank doesn't leak...my used 55g had a heater that was probably broken while it was being transported. At least the guy delivered it for free
