chrissu; Are you saying you let the scrubber fill with water? So the Turf is fully submerged?

yes, you get 3-dimensional growth that way. Mad 3D growth. I don't have the SM cleaning video handy right now but on his it's 75% full of water at 2 weeks (he was experimenting with time between cleanings and max growth potential)
That's what I'm shooting for too. I think there was a post asking about FW scrubbers but it's gone. Yes same principle except need to add Phosphate in most cases. Not good for planted tanks though, since the algae sucks out all the nutrients.

But wouldn't algae immediately cover whatever peice of acrylic/glass that the light is shining through?

As the algae grows, it 'holds' the water in the chamber. Example: Look at the water level at the bottom of the screen in this pic from a few days after the last cleaning I did:
Now look at it today: The water in the bottom area is almost to the top. By the way, this is the greenest and thickest screen by far that I've had. I need to clean it early, can't wait until tomorrow AM. This is causing a problem to surface sooner than expected. I am in the process of re-designing to accommodate for allowing the water level to rise.

I've been following along but I'm pretty stumped by the water level thing. I'm not sure what you mean, or why you would want the entire screen submerged. I thought the whole point of this design was high flow and air exchange?

Luckily, there are a couple processes that also result in the loss or transformation of ammonia. The most important process is the loss of ammonia through the uptake by algae and other plants. Plants use the nitrogen as a nutrient for growth. Photosynthesis acts like a sponge for ammonia uptake so overall plant or algae growth in the ponds can help use up ammonia. http://www.ysi.com/media/pdfs/A585-U...ture-Ponds.pdf |

Your ATS is too small. You dont need a skimmer if your ATS is large enough for the volume of your tank and the number of livestock in it.
Dont overfeed the system. And you dont need frequent water changes (10% a month will suffice.

It's always been SOP to rinse in fresh water to kill the pods.. In these flooded ATS (FATS) is this no longer a concern?

What is the optimum distance between the side of the scrubber and the screen to achieve 3D growth?

I recommend 1.5" each side, which is the same as my Santa Monica 100 ATS.

Your scrubber is ending up to be much like mine in results. My dump bucket fills up to get 3D light and water contact, much like yours, with just about the same volume of growth and the same kind of algae. I have 3 inches of water in the deep end and there is less room for growth at the other end.
What I like about that king of algae is that if you don’t feel like scraping the screen that week, you can simply grab a hand full from either side and export is complete. Of course scrapping is better, particularly when you are starting out. After a long time, that type of algae started growing on the smooth bottom of the tray so I stopped using the screen at all. I just grabbed hands full of the stuff and I was done. It tears away very nicely. |

So no pod issues?

No ...not in my case. When I yank it out, the pods come with it. The ones that stay don't do noticeable damage. Perhaps it is the particular type of algae (long and stringy like Easter basket cellophane grass).
What I grow in not typical turf algae so perhaps that pods don't attach the root, they eat evenly. I'm not really sure. |

You can fine this video of the dump bucket,
http://www.youtube.com/watch?v=mRoKX8AjEbI on my website, along with another video of the splash and some articles that were publish when I made my last reef tank in the 90’s. It also has some of what I am doing now. Take a look at it: http://asaherring.com Before you look at the video, look back at my dump bucket graphic as a review or see it on my web site. You will be able to pick out what is what a little better. |

Hi i've got some questions for all you ATS heads out there,
i was at one point thinking of doing an ATS but was put off because of the maintenance seems more practical to me to just utilise a skimmer and some macro but this thread has been making me think otherwise but i've got some questions. what do you do if you go on holiday, from what i read it is very important it is cleaned every week or 2 at most. do you get much evaporation? how do you stop it from entering your display or sump? from that last post from kcress why do you have to grow the hair algae on a screen why not grow it submerged in dedicated a tank. |

The light in the TS is so bright that the algae preferentially grows only in the TS. The result is very low to no nitrates in the Display, so there is no fuel for algae in the DT and the light is too weak. The new FATS may allow you to avoid a screen. I'll try doing this without a screen. |

If the subject is changing a little so be it. There doesn’t seem to be “anyone here but use chickens”.
I guess that a dump bucket is a FATS unit as well so I will chime in. One of the good things about agitation and/or turbulence is that you can go a lot longer without harvesting the algae because it doesn’t get matted. On the other have, dump buckets are very hard to design in the first place and you can’t buy them, as far as I can tell. As far as Kcress’s FATS, in a worst case, if a small amount of the algae died during a long vacation, I would think that the massive growth would just take up or re-absorb anything that you might think of as bad. In any case, with any good ATS design, if you really neglect the maintenance, what are the penalties that the detractors complain about? …Yellow water? …So what? Not dead corals! I left my ATS unattended for 3 months with no yellow water and healthy corals at the end of that period. I still don’t think that an ATS is any better that a skimmer. It’s just different. …but it does work and work well. I like it because I can keep food suspended longer. …and harvesting algae is much less gross than messing around with skimmate. I just wish that people had more inexpensive choices of ATS designs and manufacturers. I’m a designer with access to a machine shop but most people have to use a “scrubber in a bucket” which works great if that is an acceptable shape for your tank set up. |

So I have been doing some reading..... and I have a few questions too. Seems to me the this versus that is of no real use. The ATS setups I have seen seem unuser friendly and high maintenance. And no I am not bagging on them. Also seems like some of the criticizing of skimmers are not quite true. But my point is why not maximize what both do well?
From what I can tell the benefits of algae are in wide use today though macros in fuges. Albeit not near as efficient as a scrubber with powerful lighting. We all know the benefits achieved by letting nature do the work and using algae to clean the tank. Yet there seems to be some problems. With a ATS harvesting needs to be done weekly because the algae will die underneath in the majority of GHA ATS. So it seems that the maximum depth of GHA is only so much and that has to be harvested. Am I correct. Also the screen needs to be cleaned to kill pods because they eat the algae. Yet in a fuge that is sort of what you want. You want the algae to support pods yet at the end of the month or week you have a net export of nutrients. Sure the pods eat then get eaten then waste is put back into the water and those nutrients are not removed. But with removal of algae their is a net export. So what I am really wondering is this..... have there been any experiments done with specific algae better suited for what we want.... meaning can grow more without dieing underneath so maintenance can be prolonged? With common cheato fuges seems that a ball is just dumped in... have there been any attempts to grow cheato more efficiently scrubber style and exporting more nutrients than what is done now? Seems cheato might be better suited since more light can penetrate into the mass. I still feel skimmers are good and needed. They are much more powerful now and most folks love over sizing them. My thinking is more like running the scrubber 16 hours on and skimming when it is off. Put the skimmer on during the day time and run the scrubber over night time when corals feed and ph drops. I guess I just wondering how to best compliment each other instead of a either or thing. I tried looking up FATS which is why I'm on this tangent but could not find anything.
