Water storage tank recommendations

[BuckeyeFish]

Hello,

What do you all recommend for storing RO/saltwater? I want to be able to store 10-20 gallons at a time. I can't have too big of a storage tank since I need to keep it in a fairly small closet near my tank.

Ideally, it would be something with a valve on the bottom from which I can drain the water into a bucket for my water changes.

I use this: 20G Drum

I use the grey Rubbermade Brute trashcans, cut/drill a hole, insert a bulkhead, and attach any other fittings needed.

Most efficient is a 20 gal aquarium. Cannot move it around but need pump to pump water in and out or a scooper (1 gal milk jug with the top cut out a bit.
