I've also seen this happen on tanks that haven't ever ran a scrubber, so there must be some condition that is favorable to algae scrubber growth.

Yes, I've had this happen on my tank, & i've seen a system never having algae filtration get just Ulva growing on a screen& nothing else from the beginning. From my experience I put it down to not using any blue light, just red? Anecdotal of course, but I first ran a horizontal screen / tub style scrubber back in the 1990s & used a warm fluro tubes for illumination. All sorts of 'stuff' grew on that screen, not really what you'd want for algae filtration.

Yes it certainly can take some time for the screen to get to where you want it. This is why I found it hard to believe that a screen could get to the same stage in 13 days, as suggested in that thread on the other forum.
Like you said, it can take time, but once a screen matures there seems to be little problems from then on. At worst, growth may slow at times, but the algae just hangs in, stays green & healthy. I think this is an advantage over a fuge, & may be why some people have trouble growing chaeto. Where a scrubber screen just stays there until conditions become suitable for self seeding, chaeto just dies & then they buy more, it dies & they give up.

I came across this the other day. Haven't read it yet. You may have altready?
