The new Upflow Algae Scrubber (UAS)
Hello everybody,
This is my first post here, I currently have a 6 month old 5g tank with just a small internal filter and a powerhead as means of filtration.
I'm currently gathering ideas and equipment for my 15g tank and I would really like to keep it as simple as possible so I want to give the new ats design a shot!
Currently I have 3 designs utilizing the uas principle:
1) I call it "intank uas"

This is the simplest and smallest design I could think of.
It is just a small box for the screen, either lit by the display light or through the glass with leds.
A small pump should be used to feed the scrubber with nutrient rich water.
2) slim HOB uas.

This design has a pump in a small overflow box and the water flows through the uas much like it would in a regular HOB filter.
The Hob filter should be designed to accommodate a heater so the dt is less cluttered.
3) less slim HOB uas.

Pretty much the same as design 2, but the overflow box is just larger and could house a heater.
The screen box is just way smaller then design 2.
Some more info about this build:
either a 10x10cm screen (4x4") or a 7,5x10cm screen (3x4").
Will lit it with a diy 9x1W led fixture (6x 660nm, 2x 630nm and 1x 460nm).
All input is welcome!

Jacob.morgan78's UAS test
First, I've never had an algae scrubber of any type and have a one year old "typical" reef tank. I plan to keep my skimmer running at first but have it on a timer to only run during a certain time of day. I would eventually phase it out hopefully. I also have the typical reactors: GFO, GAC. I would phase out GFO but keep running carbon more than likely. I currently have a stand alone 10 gallon refugium with some LR, chaeto, and gracilaria... no sand. It's fed with a small MJ style pump and drains to my sump into the return section, skipping the skimmer. The UAS would go into the stand alone refugium. At first, what time a day do you think would be best to schedule my skimmer to be on? and for how long?
Now to my plan for the UAS. I'm trying to decide between two ideas. First, I could just use the airstone and tie the screen to it very similar to Scott's pictures here: Thanks Scott! http://algaescrubber.net/forums/show...t26-s-UAS-Test
My second idea would be to feed my refugium with a MJ1200 with the venturi hose attached. The water/air output of the MJ would go through vinyl tubing to the bottom of my refugium. I would attach a small diameter (undecided on size) pvc to the vinyl tube. I would cut a slot in the pvc for the water/air to be pushed out of. I would attach the screen to the pvc (undecided on how) for the water/air to move up the screen. I'm also undecided on screen size and bulb wattage. The screen would be lit from behind the refugium and be one sided for now.
My main concern here is bubbles and salt creep. I plan to insert a thin, flexible piece of acrylic into my sump to act as a baffle before my drain. It would fit snuggly into the tank against each side and rise above the water line but not above the height of the tank. I'm also going to get a piece of glass cut to fit perfectly on top of my refugium above the section before the baffle (the only part that should have bubbles in it). This glass top should keep most (I hope) of the salt creep from getting out of the tank.
I would keep the rock in there along with the other macro algaes. I would expect the UAS to out-compete them for the nutrients and things would kind of take of themselves.
A couple of things. I have a one year old and my wife is less than thrilled with me spending a bunch of time with my tank (which I'm fine with because I'd rather spend time with the family anyway). What I'm getting at is don't expect this to move along very fast. I do what I can, when I can. And, I'm battling an issue with my Apex at the moment which demands my free time. Second thing, feel free to rip my ideas a new one!!! :-) I'm okay with constructive criticism and welcome it seeing how I'm new to algae scrubbers and not an expert (yet) on reef tanks :-)
Thanks for taking a look!!!
had an idea about upflow scrubbers
on reef tanks that use an overflow and sump,,,would it be possible to capture and re-direct the bubbles coming out of the drain,,,and use them to "feed" the upflow scrubber in the sump? almost like an up side down reverse durso? No airstone or pump required! see where i am going with this? We all have tons of flow AND bubbles coming out of our drains..........
Bubbles and airstone question
Ok, apologies in advance if this has been posted and trialled already but at 37 pages thats a lot of reading!!!:
I couldn't find a wooden airstone of any length in the UK, only the blue things which disintegrate after a short period in salt water and then I had a thought....why do I need an airstone, why don't I just cut a slot in the airline and slot the screen in there? Just trialled a very basic version and it seems to work just one side really well but I literally just threw the screen and airline in a jug of water as I don't have any airline long enough!
Since airline is plastic, all you need is a stanley knife and ruler to cut and cable ties to fix screen to airline similar to what you do with a standard waterfall design. My thought is to pass the airline through some PVC piping which will cause the airline to sink to the bottom of the sump
Has this already been tried?
