This is a link to a thread just a few threads down from this one, right here in the advanced section, describing how hair algae migrated from the sump to the display.
Firstly, that link is concerning a system using a chaeto refugium, not an ATS, which do not grow chaeto. And, it was hair algae that appeared in Earwick7s display, not chaeto! But its good to know you are against using any algae as a nutrient export method, no matter the technique. Secondly, Earwicker7 said - "it is very minor, and probably not noticeable to anyone but me",,, so, it isn't anything like you described in your first post. He also has a deep sand bed and described it as - " dirtier than it should be due to using a let it grow wild methodology". I would say Earwick7's first problem is not maintaining his deep sand bed, and his fuge is probably not set up correctly, and therefore, not efficient. And, he would have a much worse "hair algae" problem in his display if he had no chaeto fuge at all.
Now, you can go ahead and explain why so many people, who don't use algae as an export method, get hair algae, and so many other algaes, growing in their displays.
I read a whole lot of threads on various forums, and the only people that suggest algae migration happens, and "happens a lot" are typically people who have never used algae filtration, but have a suspicious agenda against using it.

"Turf", of all kinds, both in the water and out, have been sooooo successful evolutionarily, due to its incredible ability to spread and conquer new territory. We build tools like weed eaters, and edgers. We build barriers like landscaping timbers, concrete blocks, and plastics. We produce chemicals like "round-up". We spend millions and millions every year in this country just to fight back "turf" and keep it from taking over.

I know, I know, I know....... "Turf algae in the oceans and our tanks is different."
No it's not.... Especially not in the way that it spreads and conquers new territory. It produces nutrient rich fragments of itself that drifts off to nourish new territory. On land, the wind is used. In water, water flow is used. Reproductive material, like seeds and spores, fallow this same path. Through this process, and others, "turf", both in the water and out, is constantly attempting to conquer new territory, and it's VERY efficient at doing so.
I don't have "turf algae" growing on my scrubber screen. No person I have built a scrubber for has "turf algae" growing on their screen. I also have never seen "turf algae" growing on the screen in any photo any participant on any forum has posted showing their scrubber screen.
Typically what is seen growing are speciec of ulva. But you, apparently, are not aware of this, or don't know the difference?

I have a couple of species of ulva growing on my screen. I did not seed the screen, the ulva grew on the screen >>> naturally<<<. It grew on the screen naturally because these species of ulva were already in my system. Either from the live rock I used. Or from coral I added. Perhaps the ulva was introduced when I used sea water for water changes. But here's the important part for you, elagance coral - never in the five years prior to installing the scrubber did I ever see any species of ulva growing in my tank, at all! It did not appear until I provided an optimum environment for it to take off.

Lets hear your explanation for that, elagance coral, and your expalnation for why the ulva hasn't ever grown in my display tank since installing my scrubber, >>>dispite me throwing in chuncks of it to feed the fish<<
Prior to installing my scrubber I had various algaes growing in the display as well as cyno. Within a month and a half of the scrubber screen maturing all algaes and cyno growing in the display were gone, completely. That was two years ago, and still no algaes at all growing in the display, >>>except for coralline algae, which was almost non existant prior to installing the scrubber, but which proliferated afterwards.

I'm not particularly interested in Adey's ATS, as I don't consider his ATS and a modern scrubber analogous. Only people who have an agenda against scrubbers bring up his model, and whats more, blame the apparent failures of his Monaco systems on his scrubbers when other public aquariums, which also had poor results, didn't use ATS'.
