This mix can be used for iron and manganese removal by oxidation. The Aquamandix (manganese dioxide) helps oxidise the iron and the sand traps the precipitate, They are similar to Birm and Filox but slightly more robust than Birm and cheaper than Filox. They requires a pH of 7 or more for iron removal and 8 for manganese removal plus a dissolved oxygen level of at least 15%. It can also be mixed with pH media to increase the pH all in one system.
This unit is supplied partailly assembled for shipping. Some assembly will be required. All components and instructions will be supplied.
This system relies on there being enough dissolved oxygen in the water to work. This kit has the option of adding an air draw kit - this puts an air pocket above the media so as the water cascades through it oxygen is adsorbed into the water.
