My Aqua Max fc 80 skimmer has stopped pumping strong enough. Water barely uses past bubble plate or surrounding water level. I have serviced the pump, took apart reassembled, ran in citric acid to no avail. The Shark 1.0 seems to be out of stock every where I know to look. BRS says Aqua Max has been bought by Aqua Ready and they haven't started stocking anywhere. This has been a nice skimmer for the past year and a half.
