• "My pool service customers are so happy. Many do not know about the hazards of Diatomaceous Earth. They appreciate that I am watching out for them."

  • "Fiber Clear is an effective and safe alternative to D.E. which is a known carcinogen."

  • "I switched from D.E. to Fiber Clear a couple summers ago and found it works better than D.E. and with less mess."

  • "Fiber Clear filters better than D.E. I use less media and I don't have to worry about inhaling D.E., which can destroy your lungs."

  • "This stuff is fantastic. It really does polish the water; there are NO particles and floaters visible in front of the pool light at night."

  • "This stuff is great. I grew up using D.E., a carcinogen and dangerous if accidently inhaled. Fiber Clear is safe, comes in a resealable bag and you use much less. The best alternative to D.E.!!!"

  • "We are very happy with Fiber Clear. Our pool is crystal clear and I save money on chemicals. I never use any clarifiers and the water is so clear that I can see the bottom of the pool, even in the deep end."
