Algal Remediation and Green Pool Recovery
When water chemistry fails or circulation lapses, photosynthetic organisms proliferate rapidly. Our remediation protocol isolates the cause, neutralises the vegetative bloom through targeted shock chemistry, and flocculates dead suspended matter for vacuum extraction directly to waste.
What is included
- ✓Total dissolved solids and cyanuric acid diagnostic tests
- ✓Coagulant and polyaluminium chloride flocculant administration
- ✓Direct-to-waste benthic sediment extraction
- ✓Filter bed disinfection and chemical washing
- ✓Algicidal eradicators targeting green, mustard, and black blooms
- ✓Post-treatment water clarification and mineral stabilization

Why Clients Entrust Us With Their Pools
Controlled chemical rescue for neglected or biologically compromised pools.
Media Preservation
Bypassing the main filter during extraction prevents dense biological sludge from destroying your filtration sand.
Definitive Eradication
We treat the underlying chemical imbalance rather than simply applying superficial clarifiers.
Avoided Refilling Costs
In most instances, our chemical intervention saves thousands of litres of water by avoiding a total pool drain.
The Clarion Standards Assurance
We do not leave plant rooms or pool sides until water balance tests sit within strict chemical parameters. If an agreed treatment fails to resolve the targeted issue, we return promptly to re-test, re-dose, and rectify the issue without additional labour charges. Pricing & payment

Clarion restored an indoor mosaic pool that had turned cloudy after a faulty dosing pump. Alistair attended personally, corrected the saturation index over two sessions, and rebuilt the dosing lines without fuss.
Charles M., Cobham, GBThe contrast with our previous contractor is pronounced. The technician arrives at 08:30 promptly, carries his own auxiliary vacuum equipment, and leaves a printed record of water chemistry on the counter.
Fiona H., Sevenoaks, GBSolid, dependable maintenance. They noticed our heat exchanger pressure was dropping before it caused damage to the burner assembly. Payment via electronic bank transfer is handled smoothly once the job is finished.
