Use double water tubes to more securely attach your winter cover to your inground pool (heavier tubes offer more security). Double water tubes are a better value because they don't "roll" like single water tubes and if one side breaks, the other keeps your cover attached. Attach them to spaced holders on your winter pool cover and use a garden hose to half-fill tubes (to allow for ice expansion).
