Jolly Gel Spa - Flocculent for Hot Tubs & Spas


Europe's No 1 Spa and Hot Tub Floucculent

Jolly Gel is a superior flucculent that has been specifically formulated for spas and hot tubs.  It was developed by MSI in response to a request from a pool retailer in Spain which had been a long-term stockist of the original Jolly Gel for swimming pools.  The pool flocculent has been on the market for 25 years and is now own-labelled for stockists in 37 countries worldwide.

The long-standing MSI stockist wanted to provide its spa clients with the same outstanding water clarity as its pool clients and asked MSI for help by providing a Jolly Gel flocculent for spas and hot tubs.

Jolly Gel Spa was ‘born’ in 2014, and quickly gained traction.  Soon the MSI salesforce across Europe was being asked for trial quantities of the product and these quickly translated into regular orders.  With demand increasing, MSI introduced Jolly Gel Spa for the global market under its own name and recently introduced own labelling to allow stockists to promote their own brands in local markets.

Jolly Gel Spa’s striking, brightly coloured packs, can be tailored to a particular company or bought in MSI packs in cartons of 12.

Each carton includes clear, easy-to-follow user instructions in three different languages – English, Spanish, and French – and a free Jolly Gel Spa button badge for the spa owner; a reminder to keep Jolly Gel Spa in mind!

See below for details on placing an own label order.



Jolly Gel Spa has gained REACH Status which certifies that all ingredients have been registered according to the requirements of Regulation(EC) No 1907/2006 of the European Parliament and of the Council of 18 December 2006 concerning the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), and its amendments. 


  • Specially formulated for spas and hot tubs
  • Easy to use
  • Because of the product’s unique formulation, minuscule particles are removed from the water
  • Works for up to 3 weeks
  • Removes algae spores
  • Reduces chlorine consumption
  • Prepares water to camera ready standards
  • Creates no clouding or residual dust
  • No aluminium included in the formulation


Every week, rinse the cartridge thoroughly to remove collected debris. This should be followed every two months by a more thorough cleaning to remove oils brought into the water.

Soak the entire cartridge overnight in hot, not boiling water, using a recognised cartridge cleaner (available from pool/spa shops).  When clean, the cartridge should be rinsed thoroughly to remove any remaining contaminants which can cause foaming.

Note that an old or unclean cartridge will restrict the water flow resulting in the filter plant switching off.  The water in the spa/hot tub should be completely replaced, on average, every nine weeks (63 days or sooner if the spa is actively used).

Before installing a Jolly Gel Spa dispenser in the cartridge area or skimmer basket, use an appropriate test kit (available from pool/spa shops) and check to ensure hygienic water conditions are correct by following these standards:

  • pH – 7.0-7.6
  • Alkalinity – 80 to 120 mg/l
  • Chlorine – 2.5 to 4.5 mg/l
  • If you are using bromine – 4.0 to 6.00 mg/l

Contact your supplier if Jolly gel Spa is required for commercial spas.



Would you like to reinforce brand awareness by having your own company branded  Jolly Gel Spa packs?  If you are a wholesaler, distributor, pool water treatment company or a pool retailer, you can place your company name directly into the hands of the spa owner.

There are two branding options: 

  1. Own label packaging is designed specifically for your company, where you chose the product name and creative design. You can provide the finished artwork or MSI can provide this service for you.  
  2. Or have Jolly Gel Spa packaging featuring your company name on the end of the packet (as shown in the illustration below).
