Means are provided in the interior of the filter element and in the flow passage for supporting a chemical. In a further embodiment of the invention, a chemical dispenser is provided for chemically treating a body of water wherein the dispenser includes an inlet for pressurized liquid and an outlet for liquid from the inlet. A flow passage is between the inlet and the outlet. A chemical chamber is provided in the flow passage between the inlet and the outlet for forming a compressible gas pocket.
