How do I clean tubing effectively?

Prof. David Walsh, Ph.D.Cleaning aquarium filter tubing is a bit of an art to really get rid of stubborn biofilm. You want to use a brush that is longer than the distance between your tubing sections that you want to clean. Push the brush in while giving it a gentle spin to break the microbial layer constantly. Finish with a thorough flush of tank water. I restore about 90% of my flow using this method at least every month.
Preparation Steps
- Measure tubing length to select proper brush size
- Prepare dedicated bucket with tank-temperature water
- Disconnect power and remove tubing carefully
- Inspect for cracks before cleaning
Brushing Technique
- Insert brush slowly while rotating clockwise
- Apply moderate pressure against interior walls
- Retract while maintaining continuous rotation
- Repeat until no debris appears on brush
Post-Cleaning Care
- Flush tubing with 2 gallons tank water
- Reinstall with secure connections
- Check for leaks before restarting filter
- Supplement bacteria if cleaning exceeded 30 minutes
Biofilm results in a flow reduction of 50% or more in neglected tubing. Because this mass of microorganisms is so thick that water pressure alone cannot dislodge it, it must be physically scrubbed away; special brushes are available for this purpose. When using these to insert (and retract), always rotate them; this way, all the surfaces inside the filter will be cleaned, and it will be restored to its original efficiency.
Flush the entire tube with tank water after brushing until several gallons have gone through, or until the tube is clear of debris. Inspect the water as it leaves the tube and reconnect carefully to prevent kinking them again. Check and record the flow after starting the motor to ensure everything is in order. Proper cleansing of the tubes will give them an additional lease of life of several years.
Always rinse your brushes with hot water the first time you set them down, and ensure they dry completely before storing them. If the bristles appear bent when pressed hard, or if the wires are corroded, discard the brush. Some people set aside specific brushes for use only in connection with the aquarium, as cross-contamination is to be avoided. Always have your tools wherever possible, and keep your own appointments.
