I would suggest a plastic tub rather than glass - lighter, cheaper & doesn't break.
One thing I would check is if that shelf is sturdy enough to hold a tank of water .... most of the premade cabinets are not built to take a lot of weight. You might want to put the water tank at the bottom & invest in a small pump.
