Reminder of the Day: Proper Flow
While not as important as how strong and near the bulb is, proper flow has shown to help a lot. Before Mrobo770131 on the UR site got things tuned properly, his flow looked like this:

Zennzzo on the MFK site, however, got it perfect from the start:

The trick is to have 35 gph (adjustable) for every inch width of the screen. And this is assuming your waterfall pipe has a slot. If your pipe uses drilled holes (not recommended) then you will use less.

to clarify - it's not an actual green bulb - I was talking about the outdoor spotlight fixture itself has green plastic (like all the other outdoor Christmas stuff). I got a 125W full spectrum bulb to go along with it.

Today's success story comes from "BearUSA" on the TR site. He did what many folks call the "combined" approach... using lots of things in addition to his scrubber to help eliminate his nuisance algae. Wish he had more pics, but here is the before:

And after:

Hi-Res: http://www.radio-media.com/fish/User...ingReef-10.jpg
Here is his setup:

And here is what he said along the way:
8/21: this guide is awesome, i,m gonna be building me one of these as soon as i get some time to myself, thanks for posting this so everyone can see and share.
9/10: what is the best way to get rid of nuisance algae, despite regular water changes and picking this stuff off the rocks it keeps growing back, my nitrates are 0ppm confirmed with 2 different test kits. my phosphates are also 0ppm with different tests. i have since set up a turf algae screen but that has only been running for a day and a half so its not working yet.
9/10: [waterfall pipe is] just an ordinary gravel vac pipe, fed by my external canister filter, the light is above at the mo i need to go out and buy some brackets and 2 light fixtures so i can have a light either side of screen, the other end of the gravel vac pipe has a water tight access plug, so i can still get in to clean the pipe. this nuisance algae just keeps on growing despite regular water changes picking it off the rocks, this stuff is ugly no matter what i do it just dont wont to disapear, this turf filter is my last resort.
9/13: i am determined to get this right but sometimes its so disheartning to see a tank that you try your very best to get things right to just keep getting covered in crap algae.
9/18: over the last couple of days i have noticed the nuisance algae i've been suffering with is eventually starting to die off. i'm sure the second 60 litre tank that i placed my calurpa green grape and cheato are starting to take up the nutrients before the nuisance stuff, i'm so pleased today that my tank is half way to looking great again.
9/20: i have done 2 small water changes whilst siphoning out as much as possible, i'm quite glad now i,m eventually getting back on track, my water is crystal clear all params are spot on, i had feared of water turning a bit yellowy with the release off the nutrients from the dying algae but i have had none of that. [...] hopefully fingers crossed i,ve got a hold on this now.
9/23: [answering "how did you do it"]: it could be a number of elements, i took on board all the advice which i received which im totally greatful for, i set up a 60 litre tank next to my main dt and filled it with a 4 inch deep sand bed, plus added culurpa green grape and cheato, i set up a temporary turf algae filter as suggested by Santa Monica in his thread under mega powerful nitrate and phosphate remover, i have continuously picked at the stuff and used a toothbrush to gently wipe over the rocks and inside the nooks and crannys, no doubt scaring my fish half to death, the only thing i haven't done yet is to replace the skimmer, i should say upgrade the skimmer, currently running a red sea pro prism, i had advice to get rid of it and get a better one. and also added another koralia 2 to improve water circulation which i placed at the bottom of dt to serge current over sand bed. increased slightly the amount of water i take out for water change, from about 90litres to about 125litres every 2 to 3 weeks. on the whole it could be any number of things i have done if not all, and once again i would like to thank all of you for your advice and recommendations.
10/6: this thread is really getting interesting now with all the different people posting and for santa monica posting pics of the scrubbers, etc. GOOD WORK SANTA MONICA KEEP IT UP
10/9: i,ve nearly cracked it, this nuisance algae have a look at these pics to see, i'm over the moon its nearly all gone.
10/16: i've been running my scrubber for about a month and a half now, n and p are zero, i have always had a zero n and p reading using the salifert test kits, but when i had that nuisance algae problem i was told the kits were registering zero because it was quite possible that the algae were taken it all in. if that makes any sense. ps another note i'd like to thank you again for your hard work and commitmant in keeping this thread a live and with the great pics your posting up, keep up the good work, without your posting of this thread i wouldn't have even known about these turf filters, so once again a BIG THANKYOU.

Update of the Day:
It's been recently discovered that the screen-wrapped-around-pipe design will clog up and stop working when the algae gets thick. It grows heavily where the screen is wrapped at the top, and blocks further flow from going down the screen. Instead the flow starts going out the ends, completely missing the entire screen, thus killing what algae was previously growing on screen. It affects different screens in varying amounts; the higher the lights are (thus closer to the wrap), the more it clogs. This is the type I'm referring to:

Today's success story is from "keifer1122" on the RS site. He got the pre-grown screen from Inland Aquatics, and put a powerful bulb on both sides (even though the screen comes only one-sided, he wanted it to grow on the other side too.) His results took six weeks. Here are his comments, highly edited for readability:
9/23: its a pre grown screen from IA. [...] my nitrates are up, its only been 2 weeks and it looks like there at a stand still, but im feeding heavily, lot of anemones in there. also where the light is the brightest theres a certain type of algae that looks like an oil spill , its got a rainbow of colors yellowish greenish brown. also no yellowing in my water. [...] i run a skimmer just cause my numbers are up there, but when there down to nuthing then ill remove.

its a 75g with 29g sump, the lights i use are 40 watt cfls comparable to 150w, but today i picked up the big daddy cfl 65 watt/300 watt comparable 3,900 lumens. so i cleaned yesterday to the point where everything was off except for the red turf that didnt come off, plus i want that to grow i think. but the screen was bare and today the screen is covered. been in for 2 weeks, not much growth the first week. but adjusted to my tank and now my first week cleaning was about the same growth that grew (lol) in one day. [...] right now i have toooo many fish... a buddy i work with was gettin out and i bought his liivestock and equip...
yellow tang
hippo tang
big royal gramma
blue green chromis
2 clownfish
mandarin
coral beauty
small bangaii cardinal
...and i only have about 35 lbs of liverock, maybe. thats pushin it. 2" sandbed, run an undersized skimmer, i think euro reef made for 55g. i test with api nitrate test, and i lost the color chart, but yellow good, red bad, im orange. and since ive been testing it looks like its getting a lighter color. [It] was usually just goin up everyday, but with the new light i think that will speed up the growing process.
9/26: i cleaned monday and today is friday, and i have to clean again. [...] the other side is getting there, still needs to catch up tho. [...] no lights on a timer, runnin it for 24/7. [although should be changed to 18 hours ON, and 6 hours OFF]. pump is on a timer, 30 [seconds] on 30 off, its just that the screen from IA was one sided and thats why the other side has to catch up.
10/23: just chimming in to say my n and p are undetectable.(!)

So essentially the important things are:
full coverage of the screen by light (18hours on, 6 off)
>35gph of flow for every inch of width of the screen
slit in the pvc pipe that runs the length of the pipe with screen fitted into it (that's what I'm not sure of)
Turn the pump on for 30seconds and off for 30seconds at a time (any better idea than some expensive tidal flooding system?)
Should I run a fan too during the pump=off period to dry the screen? what about pump and fan cycle during the lights off period too?

well, I've got mine running well... will post pics when I get around to it.
But a couple q's...
I'm not getting any growth AT ALL and it's been 5 days. Not sure why??
- my screen has great flow... it's about 16 wide and has over 500 gph flow.
- I've left my light on 24 hrs / day - it's a 125W full spectrum bulb.
Would it help to get some of the hair algae out of the display and thread it through the holes to "seed" the screen?
Any other ideas?

Is this a regular incandescent 125w bulb? If so then I'm sure it is way too hot. IMO, you should use fluorescent bulbs. How far from the scrubber is it? I didn't get any growth at all until I moved the bulb about an inch from the screen. Then it took off...

I tried to build one last night powered by the overflow into the tank. The only problem was I couldn't get it to flow down the screen without it spraying water everywhere. Any suggestions?

How did you construct yours? I used a pipe with a slit in it and glued the screen to the pipe so that water from the slit fell directly on the screen. I did not put glue inside the slit... the screen is glued to the outside of the pipe and wraps around it a little and ends right at the slit.

I cut mine so the tention from the pipe was enough to hold the plastic screen in place. I see what you're talking about. I try a bigger cut and try a "waterfall" effect and see if that works better.

Yeah, it's a "spot-gro" incandescent, and yeah - it's really hot, AND I do NOT have a fan on it currently. I see now that santamonica's example was a fluorescent, not an incandescent.
And currently the bulb is about 3 inches directly perpendicular to the screen.
So, sounds like these 2 things may be my problem, eh??

I am currently in the process of setting up a 175 gallon tank. Is it possible to start a tank without a protein skimmer. There are so many inexpensive good ideas for these algae scrubbers. I just want to get an idea what others are doing. Are most of you still running a skimmer as well or have you ditched it for the algae scrubber?

Rotary: You don't need a timer to start with. You can add one later, or build a surge device. Yes the screen usually goes into the slot, although Sly might do it differently. A fan is not needed unless you use a timer, although if you just want to cool the tank, you can use a fan anyways.
Hef: Pics would help. Also, switch to a CFL floodlight, at least 23W
Streb: Pics of your pipe would help.
Puffy: Yes a scrubber can replace a skimmer in most tanks. An exception might be a fish only tank with no sand and no rock. But for all reefs, and FOWLR that are not overload with fish, the scrubber handles all the Inorganic Nitrate and Inorganic Phosphate, yet leaves the Organics (food) in the water.

Don't ditch the skimmer, it provides mechanical filtration that you won't get with the scrubber.

If you have filter feeders, that's bad though...
I've never seen anyone keep a basket star long term in a tank with a skimmer.

Reminder of the Day: Less Maintenance
If less maintenance is a requirement, then you want an oversize screen; try 2X normal size, with 2X the number of lights. This should be able to go 2X as long before a cleaning is needed. The limiting factor might be the pods; at some point they may make big holes in the algae (or not; you will have to test). This is a great thing for someone to try out. Just remember that the additional screen space will need the same lighting that the current screen has.

Just a thought, but couldn't you run a remote submersed LED away from the pump for the pods to be attracted? pods are drawn to light so if there was a light that drew them away from the pump on the scrubber, it may resist their attacking the screen. I know this is complicating things lol.
