The ballast jug can be filled with sand, gravel, or even concrete to provide the needed weight to keep the SwimStand stable and upright. It is important to make sure all of the air is out of the ballast by filling the jug with water after filling with sand or gravel.
The Swimbrella SwimStand will float in 3 feet of water with the extension and 2 feet of water without the extension.
Feed the end of the safety tether through the hole in the side of the pole holder from the inside out. Tie a knot in the end of the tether rope to hold it in place. Run the other end of the tether up and through a gap in the ribs, then around the pole, then back down through the same gap and hook the catch in place as shown.
Use of the extension is optional and helps with stability in windy conditions by lowering the ballast jug 12 inches deeper into the water.
Always securely tighten the connections on the Swimbrella floating anchor base. It is also recommended to install a small stainless steel set screw through the cap and extension when using in deep bodies of water such as lakes.
