You can use. These are two different approaches. AF uses Life biofil as bacteria sources and its zeolite lowers down the nutrients specially NO3 through ammonia absorption. AF uses the same technique in converting NO3 and Po4 into biomass which corals can use but their zeolite dont necessarily house bacteria so you dont shake the zeolite.
Then I guess the follow up question is: where do the bacteria grow in that case? The water column?
Which zeolite system is better?
