See if you have a Harbor freight mear you, they have some good prices on pumps... http://search.harborfreight.com/cpisearch/web/search.do?keyword=pump
what size pump

I do have one near me, do shop there from time to time, just careful about what I get from them. How much head pressure or gph will I need? just cause the run is 69 feet, doesn't mean head pressure will be 69? what do I need to look for?
Safe would be 80-100 ft of head...Gph are up to you...cost vs time to fill.
300gph=5gpm not bad...600gph=10gpm pretty quick, Just don't turn it on and walk away...
With a valve or two and a couple of couplings you can siphon the old water out with the same system...but you probibly already thought of that.
Get a very heavy duty (they bulge under the pressure/weight of the water) garbage can if that's what your using or a used plastic barrel like they use for juice concentrates or food products.

Since flow rate (time to fill) is not important, the horizontal run can be neglected completely. The vertical run is all that is important when choosing a pump. Since you are pumping up a flight of stairs, any pump that will pump over 15 feet of head will do. Still, check the flow chart of the pump before you buy one. You don't want to waste your time buying one that pumps a max of 15 ft and then only get a gallon per minute. Measure your vertical run from the bottom of your barrel (or floor) up to the top of the upstairs fish tank. If your house is modern construction with 8ft ceilings, your vertical distance will be around 14-15 feet. If it is 100+ year old Post and Beam construction, you could be looking at 18+ feet.

Here is that thread that I meant to post...I put the barrel and water change/fill tool at the beginning.

CHOMPERS, I learned it as - If you have a vertical rise, then a hoizonal run followed by another vertcal rise, you had to account for the weight of the water in the horizonal run too. So that's where I'm coming from.
Also we need to run the manufacturer's suggested size pipe or hose to get the rated GPH.

Ok.
I learned it as the pressure on the bottom of a water collumn is dependent on the vertical distance to the top of the water column. Different schools I am guessing 
The horizontal head loss will affect the flow rate but it won't stop the flow like the vertical head loss. In an infinite vertical run, the pump will only pump up to the max head height. In an infinite horizontal run, the water at the end will still get out of the way.
With a standard garden hose, I agree that there will be measureable horizontal head loss but since time is not of the essence, the difference is not nessesary to worry about. That is where my thinking is coming from. (you are going to break out the Fluid Dynamics book on me, aren't you
)Don't worry, I'll embarrass you in a private mail... :j/k:
We're close enough here for government work...
Just keep the pump receipt.
Oh, and some pumps don't like their output blocked for too long, so having a shut-off at the end of the pipe (upstairs) shouldn't be used for long periods.
I wish I had a basement so I could have these kind of problems.
