High-Strength Algae Control for Severe Infestations
Lo-Chlor Tropiclear Pool Algaecide is the most powerful algaecide in the Lo-Chlor range, developed to tackle highly resistant algae.
Originally formulated for harsh tropical climates, Tropiclear delivers rapid penetration into stubborn algae growth, making it an effective solution where standard treatments struggle to restore water clarity.

Features & Benefits
- Powerful curative treatment – ideal for severe and persistent algae infestations.
- Broad-spectrum algae control – targets green, black spot, mustard, and pink algae.
- Dual-action formulation – combines a proven organo copper complex with a quaternary ammonium compound.
- Improved surface release – helps loosen stubborn algae so brushing and filtration can remove it more effectively.
- Compatible with recognised sanitisers – works alongside standard pool sanitisers and pool additives.
How It Works
Lo-Chlor Tropiclear Pool Algaecide combines an organo copper complex with a quaternary ammonium compound to deliver a powerful curative treatment for severe and resistant algae conditions.
The formulation targets algae at a cellular level while also helping loosen stubborn growth and biofilm from pool surfaces, making it easier to brush away and filter out through normal filtration.

How to Use
- Test and balance pool water before treatment.
- Reduce pH to between 7.0 and 7.2 for best results.
- Add the required dose evenly around the pool.
- Brush affected areas thoroughly to assist algae removal.
- Maintain normal filtration and clean or backwash the filter as required.
- Do not superchlorinate for 48 hours before or after treatment.
Dosage & Coverage
- Dosage: 2.5 litres treats 50,000 litres of pool water.
Important Usage & Compatibility Information
- Suitable for use in pools with recognised sanitising systems, including chlorine and salt chlorinators.
- Not recommended for use in pools fitted with ionisers or Nature2 systems.
- Do not superchlorinate for 48 hours before or after using this product.
- Regular brushing improves effectiveness, especially where algae has previously been present.
- For severe algae infestations, use in conjunction with Lo-Chlor Black Spot 900 Algaecide where appropriate.
- Foaming or a mild odour may occur during treatment and is a normal temporary effect.
- In salt chlorinated pools, fine surface bubbles may appear due to a temporary reaction in the chlorinator cell. These bubbles are harmless and typically resolve within 5–7 days, or immediately when the chlorinator is switched off.
- In some cases, combined chlorine levels may rise temporarily for 2–3 days. If this persists, Lo-Chlor Aqua-Boost may assist.
- Always test phosphate levels after algae treatment and address if required.
This product is an algaecide and must be used alongside a registered pool sanitiser. Ensure normal sanitising levels are restored and water is balanced before swimming.

Frequently Asked Questions
How does Lo-Chlor Tropiclear compare to other algaecides?
Lo-Chlor Tropiclear is the strongest algaecide in the Lo-Chlor range. It was developed for harsh tropical conditions and is intended for severe or resistant algae situations where standard algaecides may struggle.
Can Tropiclear be used as a regular maintenance algaecide?
No. Tropiclear is a curative treatment, not a long-life preventative. Once algae has been eliminated, ongoing protection should be maintained using a Lo-Chlor long-life algaecide or phosphate management where required.
Is this product safe for salt chlorinated pools?
Yes. Tropiclear is suitable for use in salt chlorinated pools. Temporary surface bubbles may appear during treatment due to a reaction in the chlorinator cell, but this is harmless and typically resolves within 5–7 days.
Why should I avoid superchlorinating around treatment time?
Superchlorination close to treatment can reduce the effectiveness of the algaecide and may increase combined chlorine levels. For best results, avoid superchlorinating for 48 hours before and after application.
Will the product stain my pool surfaces?
When used as directed and with balanced water, Tropiclear’s organo copper complex remains in solution and is formulated to minimise the risk of staining.
Why is phosphate testing recommended after treatment?
High phosphate levels can promote rapid algae regrowth. Testing and managing phosphates after treatment helps prevent algae from returning and supports longer-lasting results.
Can this product be used with ionisers or Nature2 systems?
No. Tropiclear is not recommended for pools fitted with ionisers or Nature2 systems.
