Jolly Gel for totally transparent pool water

Jolly Gel - Filter Booster!

Each pack contains 4 'cubes' of Jolly Gel.
Ideal for use in sand-filterssand-filters with SilexSilex, ZeoliteZeolite or Glass filter media.
Produces water of incredible clarity and restores the 'sparkle' to swimming pools.
Jolly Gel has a new advanced formula - each 'cube' works for 3 weeks in a pool of up to 60m³.
It's easy to use and helps maximise chemical efficiency.
Removes phosphatesphosphates (algae food). Less food = less chance of the pool turning green.

Advantages - Jolly Gel more than pays for itself!

Jolly Gels' unique formulation traps even the tiniest particles, clarifying the water to 'camera-ready' standards.
Increases filter efficiency X 5.
Each 'cube' treats a pool of up to 60m³ (15,850 US Gallons) for 3 weeks.
Removes algae and fungal spores, pollen, bacteria, viruses and phosphates. (Phosphates are algae food; less phosphates = less algae, = less chlorine used).

Reduces backwashing frequency to every 4-6 weeks instead of weekly - backwashing uses lots of water, and wastes the chemicals and heat in that water. Approx. annual saving of 40m³ of water in an average private pool.

Reduces chlorine consumption - and makes for a healthier pool for all the family.
  • Removes the tiniest particles from the water - and extends the life of the filter media and all other pool equipment.

How does it work?

When Jolly Gel is wet it feels like the slipperiest thing imaginable but, at the microscopic level, it is 'sticky'!
Jolly Gel places a porous, glutinous membrane screen over the filter media.
The sticky membrane catches the tiniest particles on contact, and holds them 'prisoner' until the filter is backwashed.
During the normal backwash cycle the sticky membrane is flushed away to the drains and the next cube of Jolly Gel continues to trap tiny particles - making the pool water cleaner and cleaner!
After a short while the water will be so clean that it becomes practically invisible!

Backwash the filter after 24 hours, then return to your normal filtration timings.

How to use Jolly Gel

Backwash the filter before using Jolly Gel for the first time.

Ensure the pool water is between pH 7.2 and 7.6 (adjust the pHadjust the pH if it is not within this range).

Remove the protective plastic bag from the cube before use.
Note:- It does not matter if the cube has dehydrated and shrunk - it will re-hydrate with no loss of performance.
  • Place the cube in the pump strainer basket (not in the skimmer).

    Run the pump for 24 hours and then backwash the filter.

    The cube will slowly dissolve as the water pases over it.

    Jolly Gel places a porous, clear glutinous membrane screen over the filter media, and penetrates the bed to an average depth of approx. 15cm. The glutinous structure catches the finest particles and also the microscopic Oocysts (eggs) of Giardia and CryptosporidiumCryptosporidium.
    During backwashing, as the filter bed lifts, the Jolly Gel membrane is flushed to waste along with the collected debris and spores.
  • Do not freeze Jolly Gel and protect it from frost.
  • Spanish Homologation Number: 12-70-4627
  • If your pool is often cloudy it is probable that the filter media needs to be changed - but Jolly Gel will give your sand-filter an extra lease of life!

  • Important Note

    When using Jolly Gel for the first time, it is important to monitor the pressure reading within the first six hours, or dependent on the filter cycle.
    The reason for this is that Jolly Gel collects suspended particles much faster than other flocculents.
    Be aware that the filter pressure will rise faster than normal and it may need to be backwashed sooner than normal. 
    When the water has been thoroughly cleansed by Jolly Gel, the normal maintenance routine can be resumed.
  • NOTE:- Not suitable for DE or cartridge filters.


    I put a cube of Jolly Gel in the pump strainer basket and it’s still there after 48 hours?

    There could be three reasons why the Jolly Gel cube is still in the basket:

    1 - You have not run the pump continuously for 24 hours.

    2 - The water temperature is below 26C (78F) – if this is the case the cube will dissolve more slowly.

    3 - You forgot to remove the cube from the little plastic bag . . . 

    The Jolly Gel cube has gone ‘rock hard’ – is this a problem? Jolly Gelcube dehydrates and hardens over time, particularly so if it has been left in a high ambient temperature.

    The cube going rock hard is not a problem. Once immersed in water it will return to its original shape and size and will perform perfectly.

    How many cubes should I use? You only need to use one cube, placed in the pump basket (not in the skimmer). For a private pool one cube will service up to 12,500 gallons or 60m³ of water.

    How often do I need to use Jolly Gel? Continuous use (one cube every 3 weeks) will ensure that the pool is always completely transparent and maximise the extended life of the filter and other pool equipment. Remember that it is not necessary to use Jolly Gel when the pool is winterisedwinterised, so 2 packs a year is sufficient for most private pools. 

  • Can I put the cube in the skimmer basket?It is not advisable to put a cube in the skimmer basket. The skimmer basket collects general debris (eg leaves). Jolly Gel is a glutinous substance, therefore, leaves and general debris will stick to it. The recommendation is to place the cube only in the pump strainer basket.
