Abstract:
1. A method for ozone-aerating and filtering fluid in a main fluid reservoir, comprising: providing an auxiliary fluid reservoir positioned adjacent to and outside of the main fluid reservoir and coupled to the main fluid reservoir via first and second conduits, said first conduit for enabling ozone-aerated and filtered fluid in the auxiliary reservoir to flow into the main reservoir by gravity when the fluid level in the auxiliary fluid reservoir is higher than the fluid level in the main fluid reservoir, said second fluid conduit for enabling fluid to flow from the main fluid reservoir to the auxiliary fluid reservoir; providing a lift tube extending below the auxiliary fluid reservoir, said lift tube having a lower end connected to the second fluid conduit and an upper end open within the auxiliary fluid reservoir; providing a filtration device housed within the auxiliary fluid reservoir for filtering the fluid in the auxiliary fluid reservoir before the fluid enters the first conduit; and
