Makes sense, the side that faces away from the window is algae free. The
algae-free rocks on the other side are shaded from the window and the fluo
(Tritons, 2*18W) by the Echinodorus.So can I kill it by leaving the lights
off?

I've seen all those articles and the ones that appeared in several
magazines, I think I know them by heart now. The only practical method seems
to be to use copper, and this will kill my platies and probably my plants.
Still, one day I might scoop out some platies and my false SAE and put a
couple real ones (if I can get any) in there.

According to the Germans water movement is the big culprit. I have almost
none now, does not make any difference.Bt the "algae" covered side in on the
side of the filter outlet, then again, so are the uncovered rocks. By the
way, the 2 sides are the same material ("Juwel" ruckwand).
