Benefits:

• Smart Guard, the patented ingredient in Smart Tabs, prevents them from dissolving too quickly so they?ll last all week or up to twice as long as ordinary tablets.
• Easy on pool surfaces, pumps, filters and other equipment; because they?re formulated to erode only when the pump is running.
• Won?t cloud water, and leaves no residue.
• Once a week application.
• Simply drop the required number of tabs (1 tablet per 50 000l water) into the weir basket ? it?s that easy and out of sight.
