I have an agp 18'x12' and am on my 2nd season. I gave up on the little pump that originally came with my pool and this year I am the proud owner of a sandfilter/pump and a heat exchanger. The heat works brilliantly. I dont see too much happening in the water with the pump though (1/3 hp). I tried to hoover the dust from bottom of pool but the 1 1/4" hoses that I use outside the pool do not attach to the inside of the pool as the connections are exactly the same size. I though I would be able to just push the hose onto the pipe. I did hold it flush to the connection and the suction worked fine but I cannot move much in this manner. Can someone please tell me what I need to buy to connect my hose to the inside of my pool. And would this be the way I connect a floating skimmer too. I'd appreciate any help offered.
