Sand Filters

Sand filters for aquaculture and industry

Ecotao offers a range of sand filter options. Sand filters can use different media other than sand such as glass media and media for iron removal.

Sand filters, Colliquip brand

These filters can be used with koi ponds with either silica or zeolite filter substrate. The use of zeolite, a natural porous stone structure material, also allows the development of the sand filter for solids removal as a biofilter for management of ammonia and nitrite in live animal recirculation systems such as koi ponds. These non-corrosive filtration systems are also used by clubs, schools, hotels and municipalities.

For biofiltration with zeolite, a mixture of silica sand and zeolite is advised.
