If you’ve never heard of a ‘glug jug’ then you are lucky to be experiencing reef tanks in our current golden age. But back in the olden days, well before there were any top off devices besides mechanical float valves, we used to use a funky contraption called a glug jug to replace evaporated water, especially in newfangled devices called ‘sumps’.
EasyTank is a modern take on the glug jug which is bringing back this simple device to compensate for evaporated water. EasyTank will be available with reservoirs of one or two liters, and uses a basic clamp to mount on the vertical edge of an aquarium, so it’ll only work on rimless tanks up to 10mm thick for the 1 liter model, or 12mm for the 2 liter model.
A simple one way valve allows air to enter when the water falls below a certain point, thereby permitting water to flow into the aquarium. With such a minute volume, the EasyTank is best suited for tiny nano and pico aquariums, and in environments that aren’t too dry. The EasyTank certainly is a niche product but sometimes it just doesn’t feel right to install a complete ATO with switches, reservoirs and feed pumps when you only need to compensate for a few cups of water at a time.
