Ok I’ve tried too get this skimmer to work again but can’t. I raise it try to lower it. Nothing. Fills to fast then over flows. Ive let run but spews water. I’ve cleaned it. haven’t been able to test water I have charged the water 10% three times this week. I got a redsea 300 skimmer and 91 gal tank that about two months old. Any advice I’d appreciate it
