Clear Flock Gel

Clear Flock Gel

Clear Flock Gel was originally manufactured for use with Zeoclere high grade filter media used in swimming pool pressure filters. This is because the standard flocculents being marketed, interfere with the ion exchange capability of this type of filter media. It was also found that because of Zeoclere’s natural structure, the collection of fines when using Clear Flock Gel was far quicker and more efficient. It was reported later by the pool trade that when used in conjunction with glass medium and silica sand medium Clear Flock Gel noticeably reduced maintenance time when compared with aluminium sulphate or liquid flocculents. There are two manufactured. To use just place the required size cube or brickette in the pump strainer. The Clear Flock Gel slowly dissolves as the water passes over it on its journey to the filter. The Clear Flock Gel places a porous, clear membrane screen over the filter media, and penetrates the bed to an average depth of some 15cm (6”). the glutinous structure will remove the finest particles of dust and algae spores. Clear

Flock Gel should not be used with cartridge filters.



  • Because of the product’s unique formulation, miniscule particles are instantly removed from the pool water.
  • Continues to work for up to 3 weeks
  • Removes algae spores
  • Reduces chlorine consumption
  • Prepares water to camera ready standards
  • Creates no clouding or residual dust
  • Places a clear membrane screen across the media to a depth of some15cm (6”)
  • Encapsulates the fine particles and holds them to the bed by means of a mild, glutinous formulation that is flushed away during backwash cycle When using Clear Flock Gel for the first time, it is important that the operator observes the pressure reading within the first six hours, or dependent on the filter cycle. The reason is that the product has a far faster collection capability than aluminium sulphate tablets, so the operator may be unaware that the pressure in the filter could build unnoticed. Once the water has been tidied by Clear Flock Gel, normal maintenance can be resumed.

Clear Flock Gel Turbidity results July 2019

The turbidity testing took place over a 5 day period and the results were impressive as you will see from the graph. Whilst test pool No 4 started out looking visually good with a turbidity reading of 0.4NTU (being 0.1 NTU below the PWTAG Standard), even so Clear Flock Gel improved the water clarity by taking the level down to: 0.27NTU which is far better than the 0.5NTU standard set by the PWTAG. Perhaps even more impressive was the results for pool No 5, as this pool was initially in a very poor condition with a turbidity reading of: 1.28 NTU. After just four days the turbidity level reduced to 0.28NTU and although there was a slight rise at the end of 5 days it was still within the 0.5NTU Standard set by the PWTAG. In fact if you take the standard of 0.5 NTU and rate it at 100% then the best results from the two pools was close to 50% better than the PWTAG standard.
