Suitable for both the Aquascape Signature Series 400 and Signature Series 1000, this faux-rock lid is designed to blend into the landscape of a pond. The Pond Skimmer Rock Lid can be placed onto your compatible pond filter to camouflage the device. This Lid can be rotated into three different positions, and fits securely on top of the Signature Series 400 and 1000 Pond Skimmers.
