I thought the idea was to improve performance. Anyway, gyre making way too much noise. Its the motor. Checked all the cages and fans. Nothings rubbing. Its on random flow so the motor noise is up and down all day. Can the 1k motor be taken apart and cleaned? Anyone dealt with this before. Frustrating. Especially when I have the exact gyre on the other side of the tank completely silent. this pump was silent before I cleaned it. anything louder than silent is unacceptable.
