We have had an above ground intex 14x42 pool for a few years and have never had a problem until now. I purchased a salt water system and attached it to our original pool pump which has worked for 5 years. The pump died last week. With one of our pool purchases from a couple of years ago, I found a 637r pump in our shed that we never needed to set up until now. The new pump has a smaller hose requirement of 1 1/4 inch whereas the existing hose is 1 1/2 inches wide. The adapters are not sold anywhere except on line so unfortunately algae built up until we were able to reconnect everything. The pool is shocked and levels are normal, however it is taking a week and the pool is still yellow-green. I thought that maybe the filter was clogged with algae and so when I went to change the filter in the pump, I noticed it was only 1/3 wet with hardly any algae!! I followed the instructions on releasing air from the pump by unscrewing the valve and waiting for the water to come through. then restarted the pump. A day later, I checked the filter and it still is only 1/3 wet. Not sure what is happening. Their does not appear t be a leak anywhere. PLEASE HELP!!
