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 contaminant buildup

Best Practices for a Clean Tank:

1. Monthly Tank Cleaning

  • Follow the directions on the package.
  • This breaks down green staining and odors, slimy film, and contaminant buildup that 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 contaminant buildup in the tank, you may use it more frequently until your tank is clean.

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 cleaning 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, green staining, 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?

We recommend using the cleaner once a month as part of your cistern maintenance routine. If you notice odor, discoloration, or contaminant buildup, clean sooner.

How much should I use?

One scoop (about 20 grams) treats 1,000 gallons. The 100 g pack contains 5 scoops and treats up to 5,000 gallons; the 500 g pack contains 25 scoops and treats up to 25,000 gallons. A free scooper is included. 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

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 surfaces at recommended dilution. 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 cleaning, no. Scoop it in, wait 1 hour or more depending on buildup, and let it work. For heavy-duty deep cleaning, especially if your tank has been sitting for a long time, drain and refill with fresh water to remove any loosened debris.

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?
