I just realized that the minimum setting for a mechanical Intermatic timer is 1 hour. I ordered a 3gpd fixed Stenner pump, that's 16 ounces minimum. Probably way too much this time of year. I normally use 24-32 ounces during the summer so I figured the 3gpd would be good (not thinking about winter). I use a solar cover, so I'd be surprised to need more than 16 ounces a week.... guess I can manually turn it on as needed until consumption hits 16 ounces (defeats the purpose!). Does it hurt to hit 7-10 ppm when it's supposed to be 4-5?
Anyone tried grinding on the on/off stops on the timer to see if a 30 minute cycle was possible?
Just had a thought, could dilute the Clorox with water 50% during the winter... or actually all the time since I have a 15 gallon drum. Wasn't wanting to buy that much Clorox now anyway.
