Aquascape skimmer and BioFalls filter mats are designed to last for several years with proper maintenance. They do not need to be replaced every year. Replace filter mats when they begin to tear, fall apart, or deteriorate.
When should I replace my skimmer filter mat?
Inspect the skimmer filter mat during routine pond maintenance. Replace the mat if it is physically deteriorating or can no longer remain intact during normal handling.
Clean the mat when excessive debris accumulates.
Check the mat if waterfall flow decreases.
Replace the mat when it begins to tear or fall apart.
A dirty but otherwise intact skimmer filter mat generally needs cleaning rather than replacement.
When should I replace my BioFalls filter mats?
Aquascape Signature Series BioFalls filter mats should be replaced after several years of use when they begin to tear or fall apart.
Clean the BioFalls filter mats no more than once per year, as directed in the manufacturer’s instructions.
Avoid unnecessary cleaning because beneficial bacteria grow on the filter mats and help maintain water quality.
Avoid chlorinated tap water when cleaning the mats, as chlorine can harm beneficial bacteria.
Replace deteriorated mats rather than replacing them automatically during annual pond maintenance.
The annual cleaning recommendation applies to Signature Series BioFalls filters used with a Signature Series Skimmer or Pondless Waterfall Vault prefilter.
Why should I avoid replacing filter mats unnecessarily?
BioFalls filter mats provide surface area for beneficial bacteria that help break down organic waste and maintain healthy pond water.
Replacing filter mats unnecessarily removes established beneficial bacteria. Keeping reusable mats in good condition helps preserve biological filtration.
Bottom line: Clean your skimmer filter mat when needed, clean your Signature Series BioFalls mats no more than annually under the documented operating conditions, and replace mats when they begin to physically deteriorate.
