Product Description

Professional-Grade Cleaning for Cleaner, Fresher Tanks

Keeping large water storage systems free from grime, odors, and buildup can be challenging. SolutionsHOCL™ Cistern & Catchment Bomb™ offers a powerful, eco-friendly cleaning solution for non-potable water tanks, helping professionals achieve consistent, cleaner results with less effort.

How It Works – The Power of Oxidation

When dissolved in water, the formula generates hypochlorous acid (HOCL), which breaks down organic residue such as algae stains and slimy film on tank surfaces through a natural oxidation process. HOCL breaks down this organic buildup, leaving tank surfaces cleaner and easier to maintain. The formula is eco-friendly and non-corrosive.

Why Professionals Choose This Formula

  • Simplified Cleaning Process: Just add the measured scoops and let the formula work, minimal manual scrubbing required
  • Easy Debris Removal: Organic material breaks loose and floats to the surface for simple removal.
  • Eco-Friendly: Made from environmentally friendly, biodegradable ingredients.
  • Tough on Buildup, Gentle on Tanks: Removes grime and odors without damaging surfaces.
  • Consistent Results:Helps maintain cleaner tanks over time, reducing future maintenance.

Key Features

  • Eco-Friendly Composition: Leaves no harmful residues.
  • Effective on Odors & Buildup: Targets organic matter and scale in non-potable water tanks.
  • User-Friendly Application:Designed for simple, hassle-free use in large-scale systems.
