Another problem rearing it's ugly head that I need to sort out soon.

Hey Anthony
Just remove the front and place it into a mild solution of hydrochloric acid to remove the CA. you then can clean the impeller and inside of the pump while it is left where it is. With all that CA your pump is only performing at probably less than 50%
I cant believe them Tunze's are still running.
They seem to blend into the whole reef so I would only clean the intakes.
