Hello there , so a few days ago I noticed my skimmer cup on my aquamaxx skimmer not filling properly . I cleaned out cup just to be sure nothing was built up in chamber or cup . The skimmer was working ok but still not foaming up properly . Yesterday there was barely any bubbles flowing up in the water and no foam going up the cup , I unplugged the yellow hose that goes to silencer and blew in it and still nothing . Not sure what could be going on? Maybe pump is no good . The skimmer is probably 6-7 months old . I took it out of the tank to clean tomorrow .
