AFM & Daisy Plus questions
What To Know Before We Start.
What is AFM filter media?
AFM is Dryden Aqua's replacement for sand in pool filters. It resists biofilm, so water stays cleaner and the pool needs fewer chemicals.
Can AFM go in my existing filter?
In most cases, yes. AFM usually replaces the sand in an existing filter. We check your filter and plant first.
What is Daisy Plus?
Daisy Plus is Dryden Aqua's wider water treatment system, combining AFM filter media with dosing and flocculation for very high water quality.
Will AFM reduce the chlorine my pool needs?
AFM resists biofilm, so the filter stays cleaner and pools typically need less chlorine to stay healthy. How much less depends on the pool and how it's used.
When is the best time to switch to AFM?
When your sand is due to be replaced anyway. We check the filter and plant first to make sure the change will work as it should.
Is AFM suitable for commercial pools?
Yes. AFM is used in commercial and private pools alike.
