I get pretty much the same if the wind is blowing. I'm in the Eastern suburbs so trees everywhere, positive is that they provide nice shade cover on hot days.
If AFM is Zeolite based, as JoyFulNoise mentioned over time it will foul up and will be difficult to clean once impurities embed themselves into the Zeolite.
I recall a number of posts on Zeolite back when I was deciding on equipment etc and decided against it due to that issue.
I have been using glass media and have been very happy with its performance. On a still night with my pool lights switched on, my water is very clear to the point where you cannot easily discern that there is water in the pool.
