I have read through several thru wall skimmer posts and do not seem to have any crystal clear answers. What I would like to do is add a thru wall skimmer to my 16' ultra index and use standard pool hose to hook this to my intex swg w/ copper pump filter . Everything I have seen talks about hard pvc plumbing, how could I connect the standard hose to intex fittings both on the pool and pump. Also I have seen the skimmer mounted in the middle of the inlet and outlet, but have also heard of using one of the existing holes and making that hole larger for the skimmer, which way is the simplest most effective? If I weren't to use an existing hole what would be done with it ?
