The use of a metal coat hanger can help if you need to lower the water in a fish tank and the noise from the filter is getting to you.
The part that was made for the filter was done by my brother. After seeing, that I made my version for the heater.

Things needed
  • Metal coat hangers
  • spare aquarium filter
  • Pliers to bend and cut the metal
The other filter helps clean more of the water. It does not get as dirty. when it does get dirty I just hit it with the hand held shower head.
Be careful, the metal is likely water soluble and metal in the tank is bad for inverts.
