Frequently Asked Questions

How Often Should I Treat My Water Tank?

For most rainwater catchment systems, using it once a month is ideal. This helps keep your tank surfaces clean and free from organic buildup

Best Practices for a Clean Tank:

1. Monthly Tank Maintenance

  • Follow the directions on the package.
  • This breaks down algae stains and odors, slimy film, and organic debris that naturally enter from roof runoff.

2. Clean Roof & Gutters the Right Way:

  • Leaves, dust, and bird or rodent droppings can dirty your water.
  • Before the rainy season or after heavy winds, clean your roof and gutters.

Important: Divert the dirty wash water away from the tank to avoid introducing debris.

3. After Heavy Weather:

  • If you notice increased droppings on the roof or algae in the tank, you may use it more frequently until your tank is clean.
  • First-flush diverters and screened inlets help keep debris out.

4. Annual System Checkup

  • Inspect the interior of the tank at least once per year.
  • Remove accumulated sediment and check screens and filters for clogs.

By diverting the dirty cleaning water and maintaining a monthly maintenance schedule, you'll help keep your tank clean and extend the life of your rainwater system.

What exactly does the Cistern Tank Cleaner do?

The Cistern Tank Cleaner is designed to remove buildup, odors, sediment, algae stains, and slimy film from cisterns and other water tanks. It helps restore your tank's cleanliness, without introducing harsh chemicals or residues. It's ideal for regular maintenance or deep cleaning.

How often should I use this product?

For best results, we recommend using the cleaner every 3 to 6 months as part of your cistern maintenance routine. If you notice odor, discoloration, or sediment buildup, it may be time to clean sooner.

How much should I use?

Each container is pre-measured for effectiveness. Always follow the directions on the package. You can scale down for smaller tanks.

What types of tanks does it work with?

Our cleaner is compatible with:

  • Concrete cisterns
  • Poly/plastic tanks
  • Fiberglass tanks
  • Non-aluminum metal tanks
  • Above-ground or underground systems

It’s a truly versatile solution for a wide range of water storage systems.

Will this damage my tank or pipes?

No. The cleaner is designed to be non-corrosive and gentle on tanks when used as directed. It removes buildup without compromising your tank's structure or internal plumbing.

Do I need to flush or rinse the tank after use?

For routine maintenance, wait about an hour, then drain and rinse. For deep cleaning, especially if your tank has been sitting for a long time, flush thoroughly after use to remove any loosened debris.

Can I use it for rainwater harvesting systems?

Absolutely! This cleaner is excellent for rainwater catchment tanks, where keeping organic growth and sediment under control is essential. It helps keep your tank clean and your system running efficiently.

Is there a strong chemical smell?

Nope! Unlike harsh bleach-based products, our cleaner has minimal odor and leaves no lingering chemical scent. It's a clean and fresh experience, not an overpowering one.

Is this a disinfectant?

No. This cleaner is formulated to clean physical buildup such as slimy film and sediment. It is not a disinfectant and does not make sanitizing or "kill" claims.
