I have an Intex 15' x 48" round pool. Came with the supper crappy 1000gph cartridge filter. I've upgraded to a monster (in comparison) 2900gph sand filter. So anyways, the pool just has the two small holes for the stock filter, doesn't have the wall skimmer. I'm now trying to figure out what I need to get to install this new filter since it came with nothing as far as adapters. Just the filter/pump and three hoses. Is there an adapter I can use on the pool to install the new hoses or do I need an adapter that attached to the pump that will allow me to use the old hoses or is there something else totally different I need? I've been looking on here and youtube and on Amazon for ideas but coming up short.
