Off-Season Cover for the Aquascape Spillway Basin 21" The Aquascape Fountain Cover Spillway Basin 21" fits the 21" Aquascape Spillway Basin to keep the basin clean and protected when the spillway feature is shut down for the off-season or an extended pause. Keep Debris Out of the Catch Basin Leaves and organic debris in an uncovered basin decompose and stain the resin over winter. They also clog the pump inlet at startup, forcing a full basin cleanout before you can run the feature again. A fitted cover takes seconds to place and prevents all of it.

Ideal for seasonal spillway installations across Canada where basins need off-season protection from leaves, debris, and freeze-thaw weathering.
