For the last year, I've been using a Fluval 406 to maintain my 75 gallon turtle tank. it's worked great up until a few days ago. I replaced a broken impeller and the parts that come wit it, and when I tried to start it up it refused to work. the water won't flow at all, not even a trickle. I can feel the motor turn on kind of, it hums a bit, but it's weak and refuses to pump any water. I put the old part back into place to see if the problem was faulty new parts, and it still refused to work. there are no clogs in the tubing or anywhere I can reach. up until now I've had no problems with it, but now i'm struggling and the old small filters I used to use can't keep up with the needs of a 9inch turtle and a dozen or so pet minnows. Does anyone have any suggestions as to what is wrong or what I can do before I send the whole thing back in?
