Lily Pipes are designed to transport the water from the external canister filter to the aquarium. Due to the fact that a glass Lily Pipe combined with water is nearly invisible the aquascape will shine in its full beautifulness without focusing on the technical equipment of the aquascape.
The moderate water flow of the Lily Pipe is ideal for the growth of aquatic plants and improves the water surface movement slightly. The flow of the Lily Pipe will additionally improve the gas and nutrient exchange in the aquascape.
A Lily Pipe can also be used for aeration at night when raised slightly above the waterline which will create more surface movement and eliminates surface scum and raises the oxygen level in the aquascape.
