This is what I did. Get a ten gallon tank or a 5 gallon bucket for that matter or anyother suitable holding container. Buy a mini jet pump either the 400 or 600 model works either one costs around $12 bucks, and then buy a nice plastic float switch from floatswitches.net each is six bucks. Splice the float switch in line with the pump lead wire fillup holding tank drop pump with a tube attached to pump the water into tank/sump and put float switch in tank/sump and set at the correct level so it just floats.

Works like a charm, going strong for the last year with no issues. 10 gallons will last for 5 days on my tank. easy and cheap.
