hello everyone, i'm installing a thru the wall skimmer on my intex ultra frame pool 16x48 and need some clarification on a couple of things. first, what do i do with the outlet connection since i will have the skimmer hose going to the inlet on the pump and second if i need to apply silicone to the skimmer to help with any leaks that might occur, where would i need to put the silicone, on the inside or outside of the pool wall and between the gasket or skimmer body itself. i'm new to this pool stuff so i could use any advice i can get. thanks for your help!
