Had some equipments breaking down over the last 2wks after commissioning my tank near to 3yrs.
1) Circulation pump for my CR, Skimz CM122, Skimz E2000 impeller shaft broken and I have to replace the whole impeller instead of just the shaft cos the inner ceramic ring/bearing to hold the shaft also worn out.
2) One of my return pump jebao dc9000 halt for the 2nd time in 2wks. Decided to change a new one, Sicce 9.0. Nv did any maintenance work on any of my pumps. Haha.
My dc pump is much more silent compared to it. But it has a 5yr warranty.
The removed pump I took out for a vinegar dip, rinse with fresh water. After drying, power it out to test again and was running. Guess I’ll keep it as spare. Worried it might halt again.
