Aqua-Hort combines copper ionization and electromagnetic pulses to control algae and fungus diseases. Treatment with electromagnetic pulses removes the hydrate layers, which greatly increases the effect of the copper ions on pathogens and algae without harming crops. Aqua-Hort systems consist of a control box, an electric treatment pipe, four sets of electrodes and a stainless steel frame that supports the components. There are many sizes and models to choose from. TrueLeaf.
