Why Choose SERIOUSTAIN REMOVER for Pool Stain Removal?
When you're dealing with stubborn pool stains, you need a solution that works. Our SERIOUSTAIN REMOVER is explicitly formulated to tackle the toughest staining problems Australian pool owners face.
 
This professional-grade pool stain remover delivers results without the cost and hassle of draining your pool.
 
Manufactured right here in Western Australia by Algaefree Australia, this product brings over 30 years of water treatment expertise to your backyard. We've developed a formula that addresses both mineral and organic staining in a single treatment.
 
What Types of Stains Does This Pool Stain Remover Eliminate?
 
1. Mineral Stains and Metal Discolouration
Our serious stain remover targets the most common mineral deposits that plague Australian pools:
- Iron stains: Those rusty brown marks that appear on pool surfaces
- Copper stains: Blue-green discolouration often caused by copper-based algaecides or corroded fittings
- Calcium deposits: White or grey scale buildup on tiles and surfaces
- Manganese stains: Dark brown or purple staining from bore water or certain water sources
This makes it an effective pool rust remover and comprehensive solution for hard water staining.
 
2. Organic Stains
Beyond minerals, SERIOUSTAIN REMOVER also eliminates organic staining from:
- Algae residue and discolouration
- Dead blackspot algae after treatment
- Leaf tannins and plant matter
- Other organic debris
 
As an algae stain remover, it's particularly effective at clearing the stubborn marks left behind after successful algae treatment with products like our POOL BLOCKS or POOL DROPS Plus.
 
Ideal for PebbleCrete and All Pool Surfaces
Finding a pebblecrete pool stain remover that's both effective and safe can be challenging. SERIOUSTAIN REMOVER is specifically formulated to work on all pool surface types without causing damage:
- PebbleCrete and exposed aggregate
- Concrete and rendered surfaces
- Fibreglass shells
- Vinyl liners
- Spa surfaces
 
The chelating agents in our formula work at the molecular level to lift stains without abrading or etching your pool's finish.

How To Use SeriouStain Remover?
The product is easy to use, simply backwash the filter and turn off the pump, then add 2 x 1.25 Kg containers in an average 50,000 litre pool and leave the stand for two to three days.
 
To boost the performance of the treatment, first add some hydrochloric acid to lower the pH of the pool, which allows the SERIOUSTAIN REMOVER to be most effective in removing stubborn mineral deposits.
 
Step-by-Step Application Guide
1. Prepare your pool – Backwash or clean your filter thoroughly
2. Turn off circulation – Switch off the pump to allow the treatment to settle
3. Add the product – Distribute 2 x 1.25kg containers evenly around the pool perimeter for a standard 50,000L pool
4. Allow contact time – Leave the pool undisturbed for 2-3 days
5. Resume filtration – Turn the pump back on and filter continuously for 24 hours
6. Rebalance water chemistry – Test and adjust pH, alkalinity, and sanitiser levels
For best results with mineral staining, pre-treat by lowering your pool's pH to between 6.8-7.0 before application. This acidic environment enhances the stain removal process.
 
Suitability and Usage of SeriouStain Remover
Suitable for all pools, this treatment removes all minerals such as calcium, iron, copper, manganese and also is effective at removing dead blackspot stains after treatment with our unique algicide products POOL BLOCKS or POOL DROPS Plus.
 
How Does This Pool Stain Remover Work?
Our serious stain remover uses a dual-action formula. The potent organic acids work to dissolve mineral deposits and break down organic matter, while powerful chelating agents bind to metal ions and hold them in suspension.
 
This prevents re-staining and allows your filtration system to remove the dissolved materials from the water.
 
Unlike harsh treatments that can damage pool surfaces or bleach liners, SERIOUSTAIN REMOVER works chemically rather than mechanically. This means effective pool stain removal without scrubbing, draining, or surface damage.
