The Skimmie Happy Tab is designed to hold two 3" chlorine tabs securely in your skimmer basket. Water flows through the slots of the Happy Tab so chlorine dissolves evenly and exposed surface area is controlled. The slotted design is engineered to provide extended release of the tabs for up to two weeks. The Happy Tab can be removed from and inserted back into the handle while installed in the skimmer basket. You no longer have to worry that undissolved tabs will fall out when you dump debris from the basket or pick through the debris to find loose tabs.
