Water Polisher

Procedure to create filter:

 1) Cut a 1L bottle in half
 2) Slide the top of the bottle onto the head of a pump that will accommodate a bottle neck
 3) Stuff the top half of the bottle with polyester filling
 4) Place in tank with the bottle fully submerged and cap side on top

How it works:

  The pump sucks up water through the polyester filling.  This filters out the fine particles in the water, returning only polished water to the tank.

Uses:

 Used for temporary situations
 Run for 1-3 hours when needed
      Typically used after a feeding or when the tank is murky 
 Remember to remove filling, as it contains debris from water that can still polite the tank
