Auto Top-up Gravity Fed Canister
Automatically replenish evaporated water and control levels in aquariums and sumps with this handy Gravity Fed Canister. Great for small to medium aquariums 60 to 250 litres or larger aquariums with less than 4 litres evaporation per week.
How it works
When water falls below the end of the level pipe the vacuum is released which allows water to drain from the canister into the tank through the drain pipe and air to flow into the canister through the level pipe. When the water level rises and covers the end of the level pipe water flow stops draining as the vacuum is re-established.
