Use suction cup hooks rated for the reef’s weight
Clean the window glass thoroughly before attaching anything
Press the suction cups firmly onto dry glass
Attach the reef to the hooks with fishing line, ribbon, or clear wire
Use adhesive window hooks if suction cups are not strong enough
Hang the reef from a curtain rod or tension rod above the window
Use removable command hooks on the window frame, not the glass
Secure the reef with lightweight string to prevent slipping
Keep the reef away from direct sunlight if it is delicate
Check the attachment regularly to make sure it stays secure
