Chloramine T reduces bacteria and parasites in pond water. During cold weather (autumn and springtime) use NT Labs Koi Care Chloramine T to keep parasitic protozoa numbers low in ponds until fish are stronger, more active and can resist them better. At low temperatures, when fish are slow, their immune system is sluggish. Parasites can compromise the fish before their defences have become fully active after the water has warmed up.
