Ultrazap Sand Filters

From R5,750.00

Using an Ultrazap fibreglass sand filter, also known as a swimming pool filter, on a koi pond is one possible way to provide filtration. A sand filtration system keeps the water crystal clear by trapping a large amount of solid waste, such as algae, microorganisms, and other debris.

Sand filters for koi ponds are small and can be hidden behind bushes or rocks. The filtered water can be sent back into the pond, through a waterfall or through a biological filter.

Description

Sand filters are generally marketed as swimming pool filters due to the misconception that they are not suitable for pond filters. Despite this labelling, they are perfectly safe to use if your water quality allows for it and are generally regarded as quite good filters. Let’s take a look at a few and what specifics make them great for koi pond usage.

How Ultrazap Fibreglass Sand Filters Work

 

Sand filters force water upward through a bed of sand. This causes “liquification,” whereby the sand takes on liquid properties. When the sand particles get suspended just right, their functional surface area increases, encouraging the growth of bacteria that break down ammonia — a nitrogen compound that koi produce as biological waste — into less-toxic compounds.

 

Sand Filters vs Bubble Bead Filters

 

Sand filter works great for a swimming pool, but when using a sand filter for a fish or koi pond, there are a few issues when compared to bubble bead filters.

  • Dirt, fish waste, and green floating algae tend to clog the top of the sand bed.
  • Backwashing of a sand filter is often once a day, sometimes more, to keep the water circulating.
  • A more powerful pump is used to push the water through the sand which in turn consumes more electricity.
  • No biological filtration. The sand bed is always under an anaerobic condition which does not allow beneficial bacteria to grow.
  • Pond owners spend more time cleaning a sand filter than a bubble bead filter.
