Lo-Chlor Filter Aid & Metal Remover is a natural cellulose fibre that coats pool filter media with a gel-like layer, dramatically improving filtration efficiency — removing dissolved metals, dead algae and fine suspended matter that standard filter media can't catch.

Standard sand and glass media filters have filtration gaps of 20–40 microns. Many fine particles, dead algae cells and dissolved metal compounds pass straight through. Filter Aid works by creating a natural cellulose coating on the filter bed that captures particles as small as 1 micron — comparable to a much finer filter medium, without changing the actual filter.

Lo-Chlor Filter Aid & Metal Remover details

• Natural cellulose fibre — coats filter media to significantly improve particle capture
• Removes dissolved metals, dead algae and fine suspended matter
• Improves filtration from 20–40 micron range down to approximately 1 micron
• Works with any filter type — sand, glass, cartridge and DE
• Fast-acting — filter performance improves within hours of application
• 300g treats a standard residential pool filter

Filter Aid works alongside Lo-Chlor Enviro-Clean — use Enviro-Clean to clean the filter media first, then apply Filter Aid to restore filtration performance to the clean media. For metal removal at the water chemistry level (rather than through filtration), Lo-Chlor Metal Solution sequesters dissolved metals in the water column.

Select your pool type or surface for specific guidance.

Apply through the skimmer box with the pump running. Allow 15–30 minutes for the fibre to coat the filter bed.
