I have owned Gures for years. The xf130 and 230 were the best ones. I'd still be using my xf230 but the impeller cage stripped and not longer turns. So I bought a pair of xf350s. One seems to now need a new shaft. The other stopped working. I am soaking in vineager. Also my Maxspect 2k gyre quit. I am also soaking it in vineagar. I am getting afraid to pull the motors out for cleaning as it seems my shaft on my xf350 needs to be replaced. They are hard to find. I'd like to run just one xf350 but it runs on an app. I cannot figure out how to use the app. I only used Ocean Gyre mode but now I have only one pump working. I cannot figure out how to run ine full time. I did get both to run a little but with the Xf350 in particular now I'm afraid to remove the magnet shaft as the other one went bad and Bulk Reef does not have the correct part as mine is a gen 1. Anybody know if I can program the app to run one only? These are good pumps why won't Maxspect deal directly with customers in the US? I need these for tank health including aggression. Basically I have lost 3 now within three months. Two I might get to working again. Possibly the third.
