Self-sinking aeration hose

A method of aerating and/or deicing a body of water with an aeration hose capable of diffusing bubbles of air within a body of water, comprising:

• a) a hose portion derived from a composition, comprising a polyvinyl chloride resin;
• a first rubber component;
• a second rubber component;
• at least one copolymer;
• at least one low temperature plasticizer;
• at least one filler comprising calcium carbonate;
• at least one heat stabilizer;
• at least one internal lubricant;
• at least one antioxidant;
• and at least one biofouling agent, wherein the hose portion comprises an outer hose portion, an inner hose portion and a plurality of hose apertures capable of receiving and diffusing pressurized air, wherein the hose is flexible and has no memory, and wherein the hose apertures are provided therethrough the inner hose portion and the outer hose portion and proportionally spaced about the outer hose portion along a length of the hose portion;
• b) a first protective layer portion surrounding an outer diameter of the hose portion, comprising a plurality of first protective layer apertures provided therethrough an inner protective sheath diameter and an outer protective sheath diameter and spaced along a length of the protective sheath, wherein the first protective layer is flexible and has memory;
• and c) a second protective layer portion surrounding an outer diameter of the first protective layer portion, comprising a plurality of second protective layer apertures provided therethrough an inner second protective layer diameter and an outer second protective layer diameter and spaced along a length of the second protective layer, wherein the second protective layer is flexible and has memory, wherein the second protective layer apertures are capable of providing communication for the air to flow to a body of water from the corresponding first protective layer apertures, and wherein the hose apertures are capable of providing communication for the air to flow from the inner hose portion to a plurality of corresponding first protective layer apertures.
