A barrier system includes a substantially vertical structure with a coating layer disposed on and circumscribing a majority of the substantially vertical structure. The coating layer has a height of at least 0.25 inches, has gouge and scratch hardness of at least 2H, and has an average surface roughness (R.sub.a) of less than 10 microns.

A downspout end cover protects and closes a lower end of a cylindrical rain gutter downspout assembly. The cover includes a body that forms a continuous hollow channel for passage of collected rainwater. An aperture at the back of the body is sized to attach to the downspout, and a front cylindrical or oval aperture emits collected rainwater. A door is rotatably attached to the front of the body at a top of the front of the body by a hinge and when closed, prevents entry of animals, insects or blown debris. The front of the body may be sloped and the door may rest against an inset ledge that protects the door and seals the downspout end cover against entry of insects and preventing detachment of the door from the body. The hinge may be offset from the back surface of the door by an arm.

A downspout end cover protects and closes a lower end of a rain gutter downspout assembly. The cover includes a body that forms a continuous hollow channel with the top and the bottom for passage of collected rainwater. The back of the body forms a first aperture sized to attach to an end of the downspout and the front forms a second aperture that emits collected rainwater. A door is rotatably attached to the front of the body at a top of the front of the body by a hinge and when closed, prevents entry of animals, insects or blown debris. A ledge provided behind the door, so that the door, when closed, rests against the ledge and does not protrude from the body, protecting the door and sealing the downspout end cover against entry of insects and preventing detachment of the door from the body.

The present disclosure relates a system for the treatment of water. The water treatment system may be linked an aquatic protection system or a water filtration system.

A barrier system includes a substantially vertical structure with a coating layer disposed on and circumscribing a majority of the substantially vertical structure. The coating layer has a height of at least 0.25 inches, has a dried film thickness of at least 5 mils, and has an average surface roughness (R.sub.a) of less than 10 microns.
