Freshwater Shotgun Treatment Four
This is for very large bodies of water and includes Potassium permanganate and Anchor Worm Treatment
Shotgun Treatment IV
Shotgun IV is for larger bodies of water where Praziquantel would be cost prohibitive so we rely on Potassium Permanganate. To bring in an Anchor Worm Spectrum we add an insect gyrase but Dimilin is better economy even if dosing is inexact.
Potassium permanganate is a caustic alkali in a powder form (in its economical form) and it's used at about 1tsp per 600 gallons of water. It brings in a specgtrum against germs, fungi, many ciliates (except Ich) and it can control flukes. It can't control agulus or lernea.
