Nutrient sponge GR was created specifically to reduce nutrients and help improve water quality without the potential side effects of chemicals. A unique granular formulation, Nutrient sponge GR has the ability to hold a high quantity of active colonies of microorganisms used to treat water. It can be deployed in the body of water to reduce nutrients present, but can also be deployed in incoming springs, creeks and streams to reduce nutrients before they ever reach a body of water. The best watershed management programs cannot stop all nutrients from entering a body of water, but now Nutrient sponge GR can be added to further increase nutrient reduction in incoming waters.
Nutrient Sponge GR can be used in many different types of applications. Aeration and circulation improve performance. Non-aerated applications will experience lower removal rates than aerated applications. Typical applications include use in wastewater lagoons, ponds, lakes and reservoirs (both in the body of water as well as incoming inlets), fish ponds and aquaculture ponds, decorative ponds, moving water systems such as creeks and rivers, circulating waste tanks, etc. Nutrient sponge GR can also be formulated for removal of many metal ions such as selenium, arsenic, lead, copper, nickel and manganese.
