Backwashing Your Filter
NOTE: Backwashing depends on how many times, how often you feed your fish and the time of the year. Before you begin backwashing check pressure gauge reading. We recommend cleaning once a week on light loads and twice a week or more on heavy loads. You must use some type of pre-filter or vortex for heavy waste (i.e. pine needles, large leaves, etc.).

2. Depress valve knob, rotate lever to backwash.
