I just coined the term FATS in this string, from the FloodedAgalTurfScrubber that was brought up in this same thread. Hence you won't find anything on it yet. LOL
But what about it is flooded? I was thinking of the velocities with the scrubber. 35 GPH per inch at only about 1/2 inch thick. To get the same velocity with a deeper tray/trough type setup would require substantial flow.
If you start up a good ATS in a system with cheato the cheato will shrivel up and die. It's flat out-competed by the ATS.
Out competed by more aggressive algae or out competed because it has superior lighting and flow? I mean we know Cheato is an aggressive invasive growing algae. Yet all we do is dump it in a container and put a spot light on it. If it had the same attention as the GHA gets in a ATS would it be choked out so easily? Probably, because GHA will grow underground

, but you get my point.
Best algae? It turns out that the best algae is the one that takes over and flourishes in your system. You cannot bring a particular one to the party and demand that It grows. On most systems the ATS will actually transition thru a few different species before the terminal resulting algae settles in. This all happens because the tank will actually change in certain nutritional ways as the ATS starts removing the nutrients.
sounds quite reasonable. Why go against Nature instead of just flowing with it.
As for a skimmer and ATS, I considered that myself, then I see that most people end up ditching their skimmers once their ATS is running well. It probably doesn't make sense to run both and maintain both if you don't need to.
Well the skimmer being a way to remove waste before it is broke down and reduce the load on the "system". Yet reading about ATS is that the algae will just pick up the slack. I can live with that but it is also not my goal to simply harvest vast amounts of algae for the trash can. Skimmers are easy to maintain as well. But if I buy the argument that protein skimmers remove food, well then perhaps aggressively over skimming the tank as seems to be the fad these days is not as productive.
What most people don't realize is that when we get fuges and big powerful skimmers going we HAVE to feed more... I argue the whole point in doing it is so we CAN feed more and more often. But ya... what is the point to increase food supply 10 fold if we just filter out half of it right off the bat. By the same token, what is the point of feeding more in a algae driven system if all we do is just grow more algae?
So perhaps relying more on a algae driven system than has been the case and having a skimmer compliment conditions instead of it being the heart of the system would be good. I mean today fuges are pretty wide spread today. Some feel the point is for macro, but fuges are for pod production. A ball of cheato thrown in is almost an after thought. If that part of the system was given more prominence then really we would sort of be talking about the same thing.
I had very low nitrates and phosphates in my system before I added a fuge. I had no nuisance algae in my display tank. I wanted a fuge for pods and micro fauna and looked at cheato growth as secondary. Just part of the habitat for pods. I wanted the cheato to mop up what ever was left over. In fact, my cheato hardly grew. It would take a grapefruit size ball two months to double in size. But I didn't care because it was not my intention to be a cheato farmer. However, perhaps I could have had a better balanced system if I skimmed less aggressively and relied more on the algae. Then at least food particles could have stayed in the water column longer and been utilized more by my corals. That's where I'm coming from. See what I mean?
