I've noted numerous references to using pucks when away from the pool for extended times which leads me to wonder if anyone has considered/suggested using a typical primary intravenous infusion set [sans needle] to passively infuse their pool with liquid chlorine. Containers for the liquid could vary but typical refillable plastic one liter [IV fluid] bags can contain 20,000 or more average "drops" of liquid and an IV set can typically deliver deliver a wide range of drops and drop sizes per minute.
I've not yet gotten a handle on the volume of liquid chlorine that forum members are using to maintain balanced pools over time, but cannot help but wonder if a simple IV infusion set would provide a shoot-and-scoot alternative for folks who are getting out of Dodge for a number of days. Inexpensive sets that will deliver 10, 15, 30 and 60 drops per ml/cc. costing less than $2 each are available to health care providers and possibly on the web to non-medical consumers.
It occurred to me that this might provide an extremely inexpensive and consistent method of delivering metered volumes of liquid chlorine over a period of many days depending the individual pools demand.
