Johnson Pump® Bio-Sok®. Completely non-toxic, environmentally-friendly method for capturing and biodegrading bilge oil and fuels leaks.
Placed inside the bilge, Bio-Sok® begins to absorb the hydrocarbons, reducing odors and biodegrading the leaking oil.
Bio-Sok generally lasts a full boating season, and when depleted you can simply throw away the outside fiber sleeve with nothing left to harm the environment!
