The Piscimar Bonflok PM-633 is a flocculant cartridge for pool skimmers, designed to tackle cloudy water and improve fine-particle retention in pools fitted with a sand or silica filter. Application couldn’t be simpler: drop the cartridge into the skimmer basket and dose at 1 cartridge per 50 m³ of water.
What the Piscimar Bonflok PM-633 is for
Even with the pump running around the clock, pool water can turn hazy when ultra-fine particles stay suspended and slip straight through the filter bed.
The Piscimar Bonflok PM-633 causes those particles to clump together so the sand or silica filter can capture them properly, restoring clarity during routine pool maintenance.
If you want to boost filtration without measuring out liquid flocculant and pouring it directly into the pool, the cartridge format makes the job straightforward.
Dosage and application method for Piscimar Bonflok
The Piscimar Bonflok PM-633 works by sitting in the skimmer basket and releasing flocculant as water is drawn through the filtration circuit.
Step-by-step application guide
- Calculate your pool volume to work out how many cartridges you need.
- Use 1 cartridge per 50 m³ of water.
- Place the cartridge in the skimmer basket – do not open it or empty the contents.
- Keep the filtration running so the product can work through the filter.
- Monitor filter pressure and backwash whenever the pressure rises or flow drops.
What to expect after applying Piscimar Bonflok
Once in the skimmer, Bonflok works gradually through the filtration cycle, helping the filter trap the fine particles responsible for cloudy water.
With the filter operating correctly, you should notice a steady improvement in water clarity over the course of the filtration run. Visible results typically appear within 24-48 hours.
Bonflok improves particle retention, but it does not replace water disinfection, pH management, or any other aspect of regular pool maintenance.
Why choose Piscimar Bonflok for cloudy pool water
The Piscimar Bonflok PM-633 is a practical choice when water cloudiness is caused by fine suspended particles that the filter alone cannot capture.
The cartridge format removes the guesswork: no measuring, no pouring liquid flocculant, no risk of overdosing. Each kit contains 8 cartridges (1 kg total), giving you multiple treatments across the pool season.

Frequently asked questions
What does the Piscimar Bonflok PM-633 do?
The Piscimar Bonflok PM-633 is a skimmer flocculant cartridge for pools. It helps prevent cloudy water by improving the retention of fine suspended particles in sand or silica filters, restoring water clarity within 24-48 hours.
How do you use Bonflok in a pool?
Place the cartridge directly in the skimmer basket without opening it. Leave the filtration running so the product is drawn through the filter. Remove the cartridge once it floats, and backwash the filter 4-5 days later.
What is the correct dose for Piscimar Bonflok?
The recommended dose is 1 cartridge per 50 m³ of pool water. For larger pools, simply use the appropriate number of cartridges to match the total water volume.
Can Bonflok be used with a cartridge filter?
No. The Piscimar Bonflok PM-633 is not suitable for pools with cartridge filters or diatomaceous earth filters. It is designed exclusively for sand or silica filter systems.
Does Bonflok replace chlorine or other pool sanitisers?
No. Bonflok is a filtration aid, not a sanitiser. It does not replace chlorine, bromine, active oxygen, pH correction, or any other element of a regular water treatment programme.
Will Bonflok clear a cloudy pool?
Yes, when cloudiness is caused by fine particles in suspension. Bonflok helps the filter capture particles it would otherwise miss, gradually restoring water transparency. Results are typically visible within 24-48 hours.
Do I need to backwash the filter after using Bonflok?
Yes. Monitor filter pressure throughout treatment. If pressure rises or flow rate drops, backwash immediately. A routine backwash 4-5 days after application is recommended to flush out the trapped particles.
Will Bonflok fix a green pool?
No. Bonflok is not an algaecide or disinfectant. A green pool requires algae treatment first – correct the underlying cause, then use Bonflok to help the filter clear any remaining fine particles once the water chemistry is back in balance.
