EDTA (Ethylene Diamine Tetra Acetic Acid) by Nico Bio Health Care is an effective pond water conditioner for fish and prawn culture. It acts as a heavy metals binder, controls plankton crash, reduces ammonia levels, and improves overall pond water quality. EDTA also helps regulate hardness and alkalinity, supports hard shell control in prawns, and maintains a healthier pond environment for better growth and productivity.
