Four-stage filtration for dependable water clarity

• Insert into the flushing chamber and confirm a complete seat for leak-free operation
• Replace every 2–4 weeks, depending on bioload and tank size
• The thickened biochemical cotton is dyed-free and chemical-free, reducing the chance of extra contaminants entering the water
