SeriouStain Inhibitor is a specialist stain-prevention treatment that locks up dissolved minerals in pool water — preventing them from plating out onto pool walls, floors, and salt chlorinator electrodes before staining can take hold.
It is an essential product for pools topped up with bore water, pools in areas of high mineral hardness, and heated pools where metals plate out particularly easily.
Available from: B&L Pumps (WA), pump shops, independent pool shops, and selected hardware stores and garden centres around Australia.
What Does SeriouStain Inhibitor Do?
SeriouStain Inhibitor works by chelating — or "locking up" — dissolved metals and minerals in pool water, keeping them in solution and preventing them from bonding to pool surfaces.
It is particularly effective at preventing the mineral discolouration caused by bore water, iron leaching, and dissolved metals, including in heated pools where metals are more likely to plate out onto walls and floors.
Regular use also prevents scale build-up on salt chlorinator electrodes, helping to extend the life of your equipment and maintain efficient operation.
Key Benefits
- Prevents mineral staining on pool walls, floors, and steps
- Suitable for bore water and high mineral hardness areas
- Removes fresh stains before they set
- Prevents scale build-up on salt chlorinator electrodes
- Contains no phosphate-based acids — unlike many competitor products — so it does not contribute nutrients that feed algae growth
- Suitable for all pool and spa types
- Simple to use — apply directly to pool water every six to twelve months
How to Use SeriouStain Inhibitor
- Simply add SeriouStain Inhibitor directly to the pool water every six to twelve months to complex dissolved minerals and keep them off pool surfaces.
- For pools with existing mineral staining or high metal concentrations, use SeriouStain Remover first to dissolve wall-based minerals back into solution — then follow with SeriouStain Inhibitor to keep those minerals in solution and prevent re-staining.
- This two-step approach — remover then inhibitor — is the recommended treatment for bore stain removal and ongoing stain prevention in problem pools.

- Pools in regions with high mineral content or iron in the water supply
- Heated pools where metals plate out more readily
- Any pool with a history of mineral staining or salt staining
- Pools with salt chlorinators prone to scale build-up on electrodes
