The Piscimar PM-142 Celnet is a liquid descaler and cleaner designed specifically for salt electrolysis cells. Over time, calcium and mineral deposits build up on the cell plates of a salt chlorinator, reducing its output and making water maintenance harder to manage. This product removes those deposits during routine equipment maintenance – it is used outside the pool, on the cell itself, never added to the water.
What the Piscimar PM-142 Celnet is for
Salt chlorinator cells work hard throughout the pool season. As water passes over the plates, calcium scale accumulates – gradually at first, then noticeably. A scaled-up cell produces less chlorine, triggers error warnings, and forces you to compensate with extra chemicals.
The Piscimar PM-142 Celnet is formulated to dissolve that scale and lift mineral deposits from the cell plates, restoring normal flow between them. It is a dedicated maintenance product for salt electrolysis systems – not a general-purpose descaler, and not a pool water treatment.
Always use it on the removed cell only, following the salt chlorinator manufacturer’s instructions for disassembly and reassembly.
How to use the Piscimar PM-142 Celnet
The cleaning process is straightforward, but the cell must be removed from the equipment before you start. Never attempt to clean the cell while it is still connected or while the system is running.
Before you begin: switch off the chlorinator, remove the cell following the equipment manual, and check the plates visually for scale or mineral build-up.
Step-by-step cleaning
- Remove the cell from the salt chlorinator as described in the equipment manual.
- Fully submerge the cell plates in the Celnet solution, ensuring complete contact with the product.
- Leave to act for 10 to 15 minutes as specified by the manufacturer.
- Rinse thoroughly with clean water to flush away the product and any loosened deposits.
- Refit the cell only once it has been fully rinsed and is ready for use.
Important: Piscimar PM-142 Celnet is a cell-cleaning product. Do not add it to the pool water and do not use it as a water treatment of any kind.
What to expect after cleaning the cell with Piscimar Celnet
After a Piscimar PM-142 Celnet treatment, the cell plates should show noticeably less scale and fewer visible deposits – provided the build-up has not been left unattended for an extended period.
With cleaner plates, the electrolysis system benefits from better flow between the electrodes and less resistance caused by mineral obstruction.
Expected outcome: regular cell cleaning helps keep the salt chlorinator running efficiently and reduces the risk of output loss caused by progressive scale accumulation.
If the equipment continues to show errors, low output, or salt/cell warnings after cleaning, other factors may need attention – such as the cell’s overall condition, salt concentration, water flow rate, or the chlorinator’s settings.
When to clean the salt electrolysis cell
Clean the cell whenever you can see scale, deposits, or visible build-up on the plates. In hard-water areas across the UK and Ireland, this can happen faster than you might expect – especially during a busy summer season when the system runs for long daily cycles.
It also makes sense to inspect the cell if the chlorinator is showing low-output alerts, cell error codes, unstable salt readings, or if the water is consistently requiring more chemical correction than usual.
Why choose Piscimar PM-142 Celnet for your salt chlorinator cell
Generic household descalers are not formulated for salt electrolysis plates and can leave residues that interfere with the cell’s performance. The Piscimar PM-142 Celnet is a purpose-built product for this specific task, with a built-in colour indicator that takes the guesswork out of the process: yellow/orange means the product is still active; once it shifts to green/blue, it is time to rinse.
- Purpose-built for salt electrolysis cells for pools.
- Removes calcium scale and mineral deposits from the plates.
- Simple immersion application – 10 to 15 minutes contact time.
- Colour indicator shows when to rinse.
- Not for use in pool water – cell maintenance only.
Always read the label and product information before use. Wear protective gloves and eye protection – this product has a pH below 1 and carries hazard statement H314 (causes severe skin burns and eye damage).

Frequently asked questions
What does the Piscimar PM-142 Celnet do?
It cleans and descales salt electrolysis cells for pools, dissolving calcium scale and mineral deposits that accumulate on the chlorinator cell plates over time. Regular use helps maintain efficient chlorine production.
Can I add the Celnet directly to the pool water?
No. The Piscimar PM-142 Celnet is a cell-cleaning product, not a pool water treatment. It must only be used on the removed cell, outside the pool, and rinsed off thoroughly before the cell is refitted.
How do I apply the Piscimar PM-142 Celnet?
Remove the cell from the salt chlorinator and fully submerge the plates in the product. Leave for 10 to 15 minutes, then rinse thoroughly with clean water before refitting the cell to the equipment.
How long should the cell soak in the Celnet?
The manufacturer specifies 10 to 15 minutes. Watch the colour indicator: the product is active while yellow/orange. When it turns green/blue, rinse immediately – leaving it longer once the colour has changed will not improve results.
Do I need to rinse the cell after cleaning?
Yes, thorough rinsing with clean water is essential. It removes both the product and any loosened scale before you refit the cell. Do not reinstall the cell without rinsing first.
How often should I clean the salt electrolysis cell?
Clean the cell whenever you see visible scale or deposits on the plates, or when the chlorinator shows low-output warnings, cell error codes, or unstable salt readings. In hard-water areas, this may be needed more frequently during the pool season.
Will the Celnet fix all salt chlorinator problems?
Not necessarily. It is effective when scale or mineral build-up on the cell is the root cause. If the chlorinator continues to show errors after cleaning, check other factors such as salt concentration, water flow, cell condition, and equipment settings.
Is the Piscimar PM-142 Celnet the same as a pool anti-scale product?
No. It is a dedicated cleaner for salt electrolysis cell plates – not a general water anti-scale treatment or a pool chemical maintenance product. Using it in pool water would be incorrect and potentially hazardous.
