About This Item

Deep Clean Your Filter Media with Visual Precision

GLB Filter Cleanse restores optimal flow rates to cartridges, D.E. grids, and sand filter beds through a concentrated granular soak. Unlike instant sprays that only address surface debris, this formula penetrates deep into the media to dissolve built-up grease, oils, and scale that backwashing cannot remove.

Designed for overnight maintenance, the solution utilizes a unique color-changing chemistry. The water turns red to indicate active cleaning power and transitions to yellow when the chemical cycle is complete or the solution is spent, eliminating guesswork from the soaking process.


Key Features

  • Visual Indicator System: The solution changes from red (active) to yellow (inactive/complete) to signal cleaning progress.
  • Universal Compatibility: Safe for use on all filter types, including Cartridge elements, D.E. grids, and Sand filter beds.
  • Dual-Action Formula: Contains both acidic compounds and detergents to simultaneously strip mineral scale and emulsify organic oils.
  • Concentrated Soak: Granular format allows for a potent, custom-mixed bath for heavily soiled equipment.
Spec Detail
Container Size 2 lbs (Granular)
Dosage Ratio 1 lb per 5 gallons of water
Application Method Deep Soak (Submerge & Wait)
Dwell Time Overnight / 12 Hours minimum

Pro Tip: For Sand Filters, this product can be used as a backwash aid. Ensure the pump is off and the system is isolated before adding the solution to the filter tank. Always rinse or backwash thoroughly after the soak period to prevent the cleaning solution from entering the pool water.

About GLB

GLB Pool & Spa has been solving backyard water problems since 1956, when microbiologist Dr. Robert Stern founded the brand on a simple idea: pool care rooted in smart science, made easy enough for anyone to use. Nearly 70 years later, GLB is one of the industry's most trusted names in specialty pool chemicals — think Algimycin algaecides, the famous Super Blue clarifier, shocks, sanitizers, balancers, and cleaners that pool professionals have recommended for generations. GLB calls itself the gold standard in pool care, and the brand has the track record to back it up. Today GLB is part of the Solenis family (Innovative Water Care), a global leader in water treatment, following its years under Lonza and Sigura. For DIY pool owners, GLB means proven, professional-grade chemistry that takes the guesswork out of clear, comfortable water.
