go shopping at supermarket, try at those cold/soft/fruit drink section.

I used to run a gravity feed auto-top off... biggest problem is to get a big container which will is rigid, because normal softer containers will just collapse inwards due to the negative pressure built up inside it...

also, the container must be 100% air tight.. one small leak and you'll get yourself a leak...

I have the similar experience with bro ervine too... been running gravity feed method for several months, never be able to seal the container completely. So end up the result is not so good, not realiable as it failed on me twice, so ended up with another method which is more reliable.

I used a electronic timer and a pump to set up a auto-top up system, works wonder since then. Only retire it after I have got my Tubby 2 months back.
