Thanks anyway. | What you have described is most likely a [Vortex] diatom filter that uses diatomaceous earth to filter micron particles from the water resulting in extremely crystal clear water. They are great, but the water flow is very fast so it is best suited for periodic use to polish the water.
I have found similar water clarity results (as mentioned in this thread) using [spun polyester] filter wool in the last stage of my filter along with Seachem Purigen which is a synthetic adsorbant that attracts dissolved organic compounds.
