  • Fatty acids (from environmental runoff)
  • Amines (from decaying plant material)

What Happens If Not Neutralized:

Product Benefits:
By neutralizing and breaking down these compounds, Cistern & Catchment Bomb™:

  • Reduces odor and slimy buildup in tanks and pipes

  • Helps keep the tank interior fresher smelling

For Roofs and Gutters

Using the Cistern & Catchment Bomb is effortless. Dilute the cleaner as directed on the package and apply it to roofs and gutters to remove contaminant buildup. Use a divertor so the contaminants do not go into your water tank.

Optimized Deep Cleaning

Most of the time, scoop it in and let it work, that is all a well-kept tank needs. But if your tank has been standing unused, or you are dealing with heavy buildup after a long season, finish the job properly: once the tank is clear, drain and refill with fresh water. Ready to use.
