Hi, I am using 3" chlorine pucks (trichlor) in a feeder next to the pool pump, to chlorinate my 10,000 gallon pool. Putting one at a time into the feeder.
I am trying to figure out how many days I can go before needing to replace the puck. My levels seem good (3-6 ppm chlorine) for the first 2 days then abruptly drop to zero.
At this point it is too much for the feeder alone to bring the chlorine level back by just adding a puck, so I have to add shock or bleach to get back up to a high chlorine level. I am trying to 'smooth out' the chlorine distribution. Currently setting the feeder level at 2 (0 is closed, 5 is max). If I set it higher it tends to eat the entire puck too quickly and chlorine levels too high.
Does anyone have a rule of thumb for how many days I should be able to use 1 puck, and what I should set the feeder setting on (1-5)?
I would like to get to a point where I replace it every 2 days, every 3 days, whatever, just some kind of a schedule.
Thanks for any help you can provide! Aaron
