Northern Hot Tub / Spa Ball Wipe

The hot tub/spa ball floats on the surface and absorbs body and suntan oils. The unique flow-through action allows water to pass but traps floating dirt and debris. The hot tub / spa-ball helps prevent foaming and scum buildup on the hot tub surface. The hot tub/spa ball will increase filter life and efficiency. When the hot tub/spa ball no longer floats it means it has absorbed all that it can and should be replaced.
