ProblemsLow Filter Flow

Low Filter Flow

The filter output weakens, reducing circulation and filtration.

Symptoms

Visible drop in output flow
Debris settling on substrate
Algae in dead zones

Common Causes

Clogged intake or media
Impeller fouled or worn
Air trapped in the impeller housing
Kinked or dirty hoses

What to Check

Intake sponge and pipe
Media condition and cleaning schedule
Impeller and shaft
Hoses for kinks and biofilm

What Not to Do

Do not clean all media in tap water at once (kills beneficial bacteria)
Do not ignore flow loss for weeks
