I want to connect the sand and salt to run at night using the in-wall skimmer. I want to have the solar run during the day using the pump and filter that comes with the 15'x48" Intex metal frame pool connected to unused intake replaced by the wall skimmer. How do I get the heated water back to the pool bypassing the sand and salt? Do I need to install another in-wall fitting, or maybe over the wall through a fountain set up?? Please help me with ideas, diagrams, any information.... One more question, will the solar filter and pump (in box filter set) be able to run water 25'??
