Filter Sand

Filter Sand

Increase your filter’s processing capacity with Shinsuke Filter Sand. Using a proprietary blend of beneficial aerobic and anaerobic bacteria, Filter Sand creates an environment comparable to the famed mud ponds of Japan, allowing your koi to develop greater color and health. This monthly filter additive can help stabilize your pond’s pH, and boost organic material breakdown, giving you the clean, beautiful pond you’ve always wanted.

$54.95 EA.


Filter Sand is available in a 500 gram bottle, which can treat a 5,280 gallon pond five times.

Benefits of Filter Sand:

  • Includes both facultative anaerobic & aerobic bacteria
  • Helps in the decomposition of organic matter
  • With monthly dosing the pH remains stable
  • Promotes the formation of an effective ecosystem


Directions for use:

  • For the first dose, shower 100g of Filter Sand for every 2,650 gallons of water directly on filer material in water
    (Filter sand is a natural mineral, and you may see white ‘sand cloud’ in the water; this is not a problem.)
  • Add air into filter for bacteria activation.
  • To maintain bacteria levels, add 1/2 dose of filter Sand into filter once a month.

**Caution should be used when medicating pond  as all medicine damages pond quality**
(Medications and treatments designed to prevent or cure koi diseases affect all bacteria, including those in the filter, which means that after use, the water quality becomes worse, and the fish are susceptible to more diseases.)

How It Works

Filter sand includes anaerobic bacteria, facultative anaerobic bacteria, aerobic bacteria, and another 10 kinds of bacteria. Each bacteria is compounded from 10,000 to 10,000,000 pcs/g.

There are over ten kinds of Aerobic bacterium in Filter Sand which include heterotrophic bacteria and autotrophic bacteria.

Heterotrophic bacteria decomposes organic matter into inorganic matter. (ie. They decompose protein, carbohydrate and fat into inorganic matter.)

Autotrophic bacteria decomposes inorganic matter into smaller matter. (ie. They decompose ammonia into nitrous acid, nitrate, and nitrogen gas.)

As the bacteria act they generate energy, as well as making vitamins and antibiotics (effective into mould) as by-products. Some of the bacteria within Filter Sand also produce an enzyme which forms structures to promote bacterial growth. In addition this is used by other living things, helping the formation of an effective ecosystem.

Remember the big differences between the natural mud pond and the hobbiest pond. In the natural mud pond there are lower stocking levels and the natural filter system of mud and sand. In the hobbiest pond stocking levels are higher, causing the filters to have to work harder making the activity of the bacteria the most important area for keeping good water in the pond.

Because hobbiest ponds are also prone to sudden changing of water quality, which may harm the filter bacteria, it is very important to add Filter Sand once a month to maintain good water .
