Abstract: An apparatus for increasing gas components in a fluid uses a controller connected to a network and client device for remote control of fluid flow rates, magnet field intensity, and pressure of fluid based on preset parameters. Conductive wire coiled around a magnet fluid treatment device generates a bidirectional magnetic flux to magnetically treat fluid in the conduit at an entry pressure. A variable frequency generator energizes the wire creating magnetic flux lines to pass through the fluid flow conduit. A gas injector receives fluid at the gas injector entry pressure and lowers the gas injector entry pressure of the fluid to a gas injector discharge pressure. A treatment chamber receives the fluid at a treatment chamber entry pressure and lowers the treatment chamber entry pressure to a treatment chamber discharge pressure. The apparatus causes absorption of increased gas component into the fluid by from 10% to at least 500%.
