The particles filtered from a 25, or 20, or 10 are invisible to the naked eye. How many microns should your filter be? Finding the right micron filter depends on your region and water supply. For example, dirt is super fine in New York, so you may need a 1micron .

Sediment filters

A sediment filter acts as a sieve to remove these particles. The important thing to keep in mind about sediment filters is that they reduce sediment. They don't remove chemicals or heavy metals or make the water taste or smell better. In general, sediment filters are rated by a "micron" number.

Sand / Media Specifiions

The ideal sand media for intermittent sand filters is a coarse sand with an effective size between mm and mm. The media sand grains should be relatively uniform in size having a low Uc value (less than ) to promote movement of water and prevent clogging.

Chimney Filter/Drain Design and Construction Considerations

filter has a soil composed of particles of two different gradation ranges, e,g, gravel and fine sand, with very little if any of the intermediate grain sizes, coarse and medium sand. Gap graded soils can be internally unstable; that is the coarse fraction does not serve as a filter to the fine fraction, and the fine fraction can be piped out

Fish waste is a real problem, but with a good filtration system and not overstocking your pond the amount of waste that settles on the bottom of your pond can be reduced. Over feeding your fish also has an impact on the sludge problem, uneaten food will simply sink to the bottom of your pond which adds to the build up of sludge.
