Iron Important To Pond Water, Bottom Quality

摘要

Iron supplementation of pond fertilizers can improve their effectiveness in promoting phytoplankton growth. Ferrous iron in bottom sediment precipitates hydrogen sulfide gas produced by microbial activity. But in ponds with acidic sediment, iron deposits on shrimp can damage gills and cause unsightly blotches on shells. Liming can reduce high iron concentrations in sediment. Well water containing ferrous iron can be treated by gravity aeration or mechanical aeration.
