Pool stains from iron, calcium, manganese, algae, and organic debris don't have to mean draining your pool.
SeriouStain Remover is a heavy-duty pool stain treatment that dissolves both mineral and organic staining from pool and spa surfaces, while the water stays in.
A DIY-friendly formula suitable for all pool types, including vinyl, fibreglass, concrete, and PebbleCrete. No specialist knowledge required.
Available from: Bunnings, B&L Pumps (WA), pump shops, independent pool shops, and selected hardware stores and garden centres around Australia.
What Stains Does SeriouStain Remover Treat?
SeriouStain Remover uses potent organic acids combined with powerful chelating agents to break down and dissolve a wide range of stubborn pool stains.
Mineral stains:
- Iron stains
- Calcium deposits and discolouration
- Manganese pool stains
- Copper staining
Organic stains:
- Algae staining
- Dead blackspot residue after algicide treatment
- Leaf stains and organic matter
It is particularly effective following treatment with Pool Blocks or Pool Drops Plus — dissolving the dead blackspot stains left behind after the algae has been killed.
Why Choose SeriouStain Remover?
Mineral discolouration and organic staining are among the most persistent pool problems — and most products only address one type.
SeriouStain Remover tackles both in a single treatment, without requiring you to drain and refill your pool.
- Removes both mineral and organic stains in one application
- No need to drain the pool water
- DIY treatment — no tradesperson required
- Suitable for all pool and spa surface types
- Works on vinyl, fibreglass, concrete, and PebbleCrete
For ongoing protection once stains are removed, follow up with SeriouStain Inhibitor to keep dissolved minerals in solution and prevent re-staining.
How to Use SeriouStain Remover
SeriouStain Remover is straightforward to apply:
- Backwash the filter and turn off the pump
- Add 2 x 1.25kg containers to an average 50,000-litre pool
- Leave the pool to stand for two to three days
To boost performance on stubborn mineral deposits, first add hydrochloric acid to lower the pool's pH. This allows SeriouStain Remover to work at maximum effectiveness before application.
Frequently Asked Questions
Does SeriouStain Remover work on manganese pool stains?
Yes. SeriouStain Remover is formulated to dissolve manganese along with other common mineral stains including iron, calcium, and copper. For severe manganese staining, lowering the pool's pH with hydrochloric acid before treatment will improve results.
Do I need to drain my pool to use SeriouStain Remover?
No. One of the key advantages of SeriouStain Remover is that the treatment is applied directly to the pool water — no draining required.
Is it suitable for fibreglass pools?
Yes. SeriouStain Remover is suitable for all pool surface types including fibreglass, vinyl, concrete, and PebbleCrete.
Can I use it after treating blackspot algae?
Yes — and it is specifically recommended for this. After treating blackspot with Pool Blocks or Pool Drops Plus, dead blackspot stains often remain on surfaces. SeriouStain Remover dissolves these residual organic stains.
How much do I need for my pool? Two 1.25kg containers are recommended for an average 50,000-litre pool. Increase the dosage for heavily stained pools or high mineral concentrations.
What should I use after treatment to prevent staining returning?
Follow up with SeriouStain Inhibitor, which chelates dissolved minerals and keeps them in solution — preventing them from re-bonding to pool surfaces.
