Hey sorry guys, the media like siporax, matrix, or yes, AF Bio Fil is that they can be placed passive, active, in media box, in media bags. It is a very similar material to matrix, pomice or pumice, if you will. The AF Life Bio Fil comes pre-loaded with bacteria, so this begins to work very quickly, versus weeks and weeks like other medias. The amount you run is up to you, like other biological media, it goes the distance, and can you really ever have enough? But, on the directions, it is 1 liter per 400 liters, in a good flow area, to be replaced by 10-20% replaced every 6 weeks. I have 2 liters running in a TLF 550 reactor with good flow. I also use 5 liters of siporax in the AF 150 reactor. Bio Fil is hard to find right now, mainly because of the demand, and production time. Probably as we get into the new year, it will become more available. Yes Europe seems to have more available.

"How much of it do I run and at what flow rate? In addition what flow rate should I have going through the zeolites when using them in their own reactor with it's own feed line?"
When I started use of Zeo Mix, there was really no instructions, so I mimicked the flow recommendations of Zeovit. I now use the stack method, so I set the flow rate until Phosphate Minus tumbles. I would start with matching the gph to the amount of media. If you use a liter, probably good around 100gph. You could of course do your own experiment and measure nutrients and how they test with less versus more flow. This is copy paste off AF Website.
" There is no need to shake zeolites. We recommend to keep Zeo Mix in for example Media Reactor in good water flow: 300-500l/h."
Have a great weekend Adam!
