We have the Intex Ultra 12x24 with SWG and a sand filter. Right now in coastal AL we need to run the filter 24/7. The problem with this pool is that the timer kicks on the SWG and filter together and runs them for a set time. And then it turns both of them off. I want the filter to continue to run, as we have to go out and manually switch to filter,.then remember to switch back to SWG each time. It's a huge hassle, and we'd also like to be able to leave town without worrying about it. Is there a way to install another timer on the filter with this setup?
