So my Mighty Jet return pump on my IM 20 gal peninsula suddenly started making a loud grinding sound, as if there’s sand or something stuck in the impeller. I tried cleaning it but I have 0 clue how to get to the impeller. Does anyone know if access to the impeller is possible? So many things are going wrong with my tank it’s the cherry on top now. If the impeller cannot be accessed should I soak in vinegar or something? Thanks. Dont want to have to replace it
