Water storage

[Magickiwi]

I use a 50 gallon garbage can with wheels and a hinged lid. Whoever designed it must have known what aquarium owners would want because there's a recess in the bottom of the can that my pump fits in which allows me to pump almost every drop out. By the time the pump begins to complain there's only a liter or two of water left.

I used a graduated 5 gallon pail to mark the 25g and 50g points so my measurements should always be pretty close. I also thought about tapping a drain on to it but submersing the pump is more convenient at the moment.
