How to Remove Organic StainsUpdated 34 minutes ago
In Australia, it’s common to find brown, green, or yellowish stains on your pool surfaces, especially if you have gum trees, bottle brushes, or other native plants nearby. These stains are caused by tannins and organic debris settling on the floor and walls. Here’s the expert-recommended method for removing them.
1. Identify the Stain
First, confirm you're dealing with a stain from natural debris. These typically look like:
Brownish or tea-coloured patches from leaves and tannins.
Faint green or yellow marks left behind after clearing algae.
Patches of discolouration in areas where leaves and garden runoff collect.
2. The Australian-Made Solution
For these types of stains, a standard shock treatment isn't always enough. You need a targeted treatment that can break down the stain directly. The Water TechniX Stain Remover is an Australian-made blend of organic acids tested for local conditions and is highly effective at lifting these stubborn marks from all pool surfaces.
3. How to Treat the Stains (Step-by-Step)
To ensure the treatment works correctly, you must follow these steps precisely. This method involves temporarily lowering your chlorine and pH to allow the stain remover to work directly on the stain.
Step 1: Prepare Your WaterThis is the most critical step. Before adding the stain remover, you must:
Lower Free Chlorine Level to 0 ppm. High chlorine will prevent the stain remover from working. You can let the chlorine level drop naturally or use a chlorine neutraliser.
Adjust pH to 7.6 This makes the stain remover most effective. You may need to use a pH reducer to lower the level.
Turn your pool pump OFF. The water must be still.
Step 2: Apply the Stain Remover
With the pump off, carefully sprinkle the Water TechniX Stain and Rust Remover powder directly onto the stained areas.
For widespread staining, use 1kg per 50,000L of water, broadcasting it evenly across the pool surface.
For spot-treating, apply a small amount directly to the specific stain.
Step 3: Let it Work, then Brush
Allow the product to sit undisturbed on the stains for 1-2 hours.
After the time is up, use your pool brush to gently scrub the treated areas. The stains should lift away easily.
Step 4: Rebalance and Filter
Once the stains are gone, turn your pump back on to circulate the water.
Run the filter for at least 24 hours.
Re-test and rebalance your water to its normal operating levels (pH 7.2-7.6, Alkalinity 80-120 ppm, and Free Chlorine 1-3 ppm). A post-treatment Oxi-Shock is a great way to restore water quality without affecting chlorine levels.
Important Note: Tough stains may require repeat doses.
4. Preventing Future Stains
Once your pool is sparkling again, keep it that way with these tips:
Maintain a consistent chlorine level to break down organic matter as it enters the pool.
Skim your pool regularly, especially after windy days or lawn mowing, to remove leaves before they sink and stain.
Trim back overhanging branches from gum trees and other plants that drop debris.
Brush your pool weekly to ensure nothing has a chance to settle on the surfaces.
