Meet the revolutionalry new SIL-KLEER filter powder for diatomite pool filters using either chlorine or biguanide sanitizing systems.

• Sil-Kleer greatly reduces filter plugging with biguanide chemicals. No more chiseling out solid cake. Up to 4 times the cycle life! Superior cake release for shorter backwash cycle and less water loss.
  
• Greater filtering capacity gives diamond like water clarity longer. Fewer filter charges!
• Lightweight for more even distribution. No settling. Less bag breakage.
• Non-toxic. 99.9% silica free.
• Excellent distributor and retailer margins. Call for the name of your nearest distributor.

For the swimming pool owner who wants crystal-clear water with minimum effort and cost, Silbrico Corporation presents SIL-KLEER Filter Powder." This filter medium offers excellent benefits over diatomaceous earth.

Non-Toxic/ Non-Hazardous
SIL-KLEER, unlike the other filter media, is a non-toxic volcanic glass mineral powder with less than 1/10th of 1% free silica.

Excellent Clarity
SIL-KLEER gives cleaner, brighter, more sparkling pool waters.

Inert & Neutral
SIL-KLEER is chemically inert and neutral, pH-6.8 to 7.2 with practically zero solubility.

Lightweight - Easier to Handle
SIL-KLEER is lighter and easier to handle and use. One 10 pound bag of SIL-KLEER is equal in volume and performance to one 25 pound bag of diatomaceous earth.

Improved Backwashing
Because of the physical characteristics of SIL-KLEER, the cake is not mud-like and backwashes off the filter cloth or screen more completely. The SIL-KLEER cake flushes out of the filter without clogging pipes or drains.

Optimum Porosity
SIL-KLEER is a volcanic glass mineral, produced by thermal expansion of highest-quality Volcanic deposits. Carefully controlled processing produces microscopic, sharp, irregular particles with required void spaces for optimum porosity characteristics ideally suited for swimming pool filtration.

SIL-KLEER Precoats Evenly
Because of the lightweight characteristics of SIL-KLEER, the particles are easily suspended in the water to distribute and precoat more evenly.

Excellent Cycles
SIL-KLEER has optimum particle size distribution to give excellent filtration cycles with excellent clarities.

More Economical
SIL-KLEER substitutes for diatomaceous earth on an equal volume basis; use of SIL-KLEER saves 50 percent of the weight of diatomaceous earth.
