The Piscimar Grease Killer PM-620 is an ultra-concentrated enzymatic clarifier for pools, formulated to biodegrade organic matter, fats, tanning oils and sunscreens that build up in the water. It helps restore water clarity, reduces residue at the waterline and eases the organic load on your filtration system.
What does the Piscimar Grease Killer PM-620 actually do?
Every pool that gets regular use collects invisible contamination: sunscreen residue, body oils, tanning lotions and other organic compounds that standard chlorine struggles to break down efficiently. Over time these accumulate at the waterline, leave marks on swimwear and clog filter media – reducing both water clarity and filtration performance.
The Piscimar PM-620 Grease Killer tackles this at the source. Its enzymatic action – driven by lipase – breaks down fats and organic compounds directly in the water, rather than simply masking them. The result is cleaner water, a cleaner waterline and a filter that doesn’t have to work as hard.
It is not an algaecide, not a disinfectant and not a shock treatment. It does one job and does it well: organic matter and grease removal for pools.
Dosage and application guide for Piscimar Grease Killer PM-620
Before applying, check that your pool shows signs of organic build-up – a greasy waterline, cloudy water linked to bather load, or filter performance that has dropped despite correct chlorine levels. These are the conditions where the Piscimar PM-620 Grease Killer delivers the most noticeable improvement.
Recommended dosage
- Initial dose: 1 L per 100 m³ of pool water.
- Weekly maintenance: 0.5 L per 100 m³ every week.
- Note: always follow the dosage printed on the label of the pack you have purchased, particularly if it differs from the above.
Step-by-step application
- Calculate your pool volume so you can measure the correct amount.
- Distribute the Grease Killer evenly across the pool surface, respecting the dosage above.
- Run the filtration continuously to circulate the product throughout the pool.
- Monitor water clarity and the waterline over the following days.
- Repeat weekly in pools with heavy bather loads or frequent sunscreen and tanning oil use.
What to expect after applying Piscimar Grease Killer PM-620
Once applied and circulated through the filtration system, the Piscimar PM-620 Grease Killer begins breaking down organic compounds in the water. Most users notice an improvement in water clarity and a cleaner waterline within a few days – especially in pools that see heavy use during the summer season.
In pools with high bather traffic – family pools in regular use from May through September, for example – weekly maintenance doses help prevent organic matter from accumulating between treatments.
The Grease Killer improves clarity and degrades organic matter, but it does not replace disinfection, pH management or routine pool maintenance. Think of it as a specialist support product, not a standalone treatment.

Frequently asked questions
What is the Piscimar Grease Killer PM-620 used for?
It biodegrades organic matter in pool water – specifically fats, sunscreens and tanning oils that build up at the waterline, stain swimwear and reduce filter efficiency. It works through enzymatic action rather than chemical oxidation.
Will it remove the greasy ring around the waterline?
Yes. The Grease Killer breaks down the fats, sunscreens and tanning oils that cause waterline residue and staining. Regular weekly doses help prevent the ring from returning in pools with heavy bather use.
What is the correct dosage for Piscimar Grease Killer PM-620?
Piscimar’s official figures are 1 L per 100 m³ as an initial dose, then 0.5 L per 100 m³ weekly for maintenance. Always check the label on the pack you have purchased, as packaging instructions take precedence.
How do I apply Grease Killer to my pool?
Distribute the product evenly across the pool surface at the recommended dose, then run the filtration for at least 8 hours to circulate it throughout the water. No pre-dilution is needed.
Does Grease Killer replace chlorine or other pool treatments?
No. The Piscimar PM-620 Grease Killer is a specialist clarifier, not a disinfectant. It does not replace chlorine, bromine, active oxygen, pH correction or filtration – it works alongside your existing treatment routine.
What is the difference between Grease Killer and Goldenflok?
Grease Killer uses enzymatic action to break down fats and organic compounds in the water. Goldenflok is a coagulant that groups fine particles together so the filter can capture them. Piscimar recommends using both together for best results.
Is Grease Killer compatible with cartridge filters and salt pools?
Yes. It is compatible with all common filter media – sand, glass, cartridge, diatomaceous earth and zeolites – and is also suitable for salt electrolysis pools.
