Looking for ideas for reservoir tanks that will be low profile, preferably one that will have a low spot for the pump, so it can actually pump most of the water out of it. I have a 50 gallon tote, but the pump cannot get the last 3-4 inches of water out of it, which is quite a bit because of the large area it takes up. I thought about a trashcan, but they are only 32 gallons and may not work as far as room is concerned. One that is 18" or less would be great so as to fit underneath a table... But something tall and skinny MIGHT be ok. Any suggestions?
