Based on the description, it sounds like the Phosphate Absorber is Granular Ferric Oxide (GFO). It will be interesting to see if they market this product differently than their already successful GFO product RowaPhos. The other Aqua Crown products sound like worthy additions, but the Po4 Absorber is likely to cause some cannibalization. No word on when these will be available in the States, but they can currently be found for sale on many European online stores.
Thank you to Tomasz C. for the photos.
