Apparatus and Method for Coating Diatomaceous Earth Filter Grids

A method of dispensing diatomaceous earth within a pool comprising:

• placing a distal end of an outer section over an outlet of a skimmer of the pool, the distal end of the outer section having an aperture;
• inserting a holder into an open proximate end of the outer section, the holder including,
• a canister having a closed proximate end and an open distal end;
• diatomaceous earth contained within the canister;
• and
• a punctureable seal over the open distal end of the canister for containing the diatomaceous earth within the canister;
• rotating the holder relative to the outer section to cause a cutting element to cut the seal and dispense the diatomaceous earth.

A system of dispensing diatomaceous earth within a pool comprising:

• a holder including,
• a canister having a closed proximate end and an open distal end;
• diatomaceous earth contained within the canister;
• and
• a punctureable seal over the open distal end of the canister for containing the diatomaceous earth within the canister;
• an in-line injection unit having,
• an inlet coupled to the pool;
• an outlet coupled to a pool filter;
• a drop shoot coupled between the inlet and outlet and configured to receive the canister;
• the drop shoot having a first and second end, with the first end having a closeable lid and the second end having an aperture in fluid contact with the inlet and outlet;
• the drop shoot having a cutting element located proximate the second end;
• wherein when the holder is inserted into the drop shoot, the cutting element punctures the seal over the distal end of the canister and dispenses the diatomaceous earth from the canister through the outlet and into the pool filter.
