Common questions
How often should I clean an aquarium filter?
Every few weeks, or when flow drops. Rinse media gently in removed tank water rather than tap water to keep beneficial bacteria.
How much flow does a planted tank need?
Moderate, even flow that gently moves plants across the tank helps distribute CO2 and nutrients without blasting fish.
