Poolmaster In-line Automatic Chlorinator for 3" Tablet

I love this chlorinator. It holds three 3" tabs and has a twister adjuster to regulate how fast you want your tabs to dissolve. It floats evenly and is designed to 'clear' the vacuum hose that attaches to the side of the pool so it doesn't get 'hung up' at that location. The size is the actual size of a Mallard so it looks realistic. It actually fooled a squirrel in the backyard. When the duck floated by, the squirrel stood up on its hind legs but I wasn't fast enough to get the picture. It's relaxing to watch. It came with helpful instructions on how to adjust the water flow vents where the tabs go and included a warning about mixing different tabs.
