Do anything you can to make it 2-sided.

I am going to install my scrubber in my refugium which has 1 side that uses blue acrylic so I cant mount a lamp there. I will add a light on that side but it not be optimum.

Are there any suggestions for getting more even flow across the screen?

Depends on the type of uneven flow you are getting. Can you describe the issue a bit? Meaning, are you getting an arc of flow so there is a lot on one end but not much on the other, or less on one face vs the other, dead flow spot in the middle, etc?

Pics always help

I always find these growth pics amazing. Even after a year of use now, I still only get mildly green and very slimy algae on my screen. No matter how long I let it go for either, just slimy brownish green algae.



I have mine setup as a box with 2 2W grow lights(you know those ones santa monica hates so much). The light are on a schedule opposite of each other, where one is on from midnight to 11 am, and hour break, then from noon to midnight on the other light.



I certainly have plenty of nutrients as my no3 and po4 measure 16 and .2 respectively.



I just have no idea why I only get this slimy snotty algae that just wipes off the screen, as opposed to nice lush green algae I see on most of these scrubber pics.



Right now I have no idea why I'm running a scrubber as it's pretty pointless. Display has plenty of algae growing, and none on my scrubber screen.

You only have 2 2 watt lights? How big is the screen?

What is the spectrum of the red LEDs?
Are there any blues, if so how many blues & reds?
Size of screen?

Spectrum of LED's, no idea they are those spot grow lamps you find on amazon that SM hates so much. They have 0 blues in them, all reds.



Screen size is 6x6, 2 cubes a day or 24 inches 2 sided, or now that I reread zoho, do I have 48 inches since it's lit on both sides?

6"x6" screen is 3 cubes

All red is what I use, but I know mine are 660nm, cree
My "funny" growth pic is above.

Your light may be poor quality & not 660nm spectrum. Perhaps try a new better quality light on one side & see how that goes?

I calculate that it should be a genuine 9watt to 14watt light per side.

If you're referring to the ones that use an array of a huge number of low-wattage diodes, that could be a spectrum and intensity issue.

Wattage (actual) is the thing that would define this best. Plug the fixture into a kill-o-watt or find some way to measure actual wattage draw, that's going to tell you a lot.

Here's my writeup on the subject

These are the specific ones I bought.



http://vi.vipr.ebaydesc.com/ws/eBayI...1&secureDesc=0


It seems as though they use 1W LED's. 16 red, 4 blue @ 20W.

Yes, I've read that at length many times when I was setting my scrubber up. Also asked you and SM about the lights, and at the time they were sufficient.



Doing some reading today, perhaps I'm overlighting the screen? Cut back on my time or as previously suggested do like an hour on, and 15 minutes off?

That's the marketing side of things, I discuss that in my write-up. Plug that into a meter and it will likely pull less than 10W. "1W Rated" does not equal 1W actual power out/consumed, it's a label

I'll have to go back and find that post, if the screen is 36 sq in and you have 0.25 w/sq minimum on each side, that's 9w, that's likely where you are at, so that would makes sense that I would say they were sufficient. But I would have expected myself to say "minimally sufficient". I shall have to go back in time and slap myself a bit.

Actually hooked up to a kill-o-watt and they draw 15W. So not quite the 20W thats advertised, but not as terrible as you thought either.



Still doesn't explain why I'm only getting slimy snotty algae, and not the nice lush green I see on most growth pics in here. I certainly have some nice lush green in my display.


It started to get a nice lush growth, but then the next week it went back to this snotty growth, and anything(GHA) that was attached to the screen, has now rinsed off and I'm dealing with an almost clean screen now. With the algae getting washed off after scraping I'm starting with a pretty clean screen every week now.



Could it be too much flow over the screen? I haven't measure it since I started paying with it, but I know I started out at just under 200gph(roughly where it should be (35gph x 6" = 210).

I'm guessing you might have mentioned that before also. Can't recall, thread too long!

Do you have a few current pics of the setup and the screen with growth (before cleaning)?

Pics...


basic box style ATS





Just some plumbing pics with gate valve for fine flow adjustment






Inside of box with slot pipe and screen



Growth isn't much as I just cleaned it off a couple days ago. On the edges you can see where I used to get some lush green growth, but the rest of screen just wipes off the slimy snotty stuff. Nothing attaches on the rest of the screen. Perhaps too much light?

That is a pretty good example of a hotspot - it's not a uber intense one, because you can see some green in the central area, but when you have that "outline" of filled-in GHA, that's a dead giveaway.

Multichip fixture? The one with the reflector/center chip, right?

yes thats the type of light.



I cannot move them away, but perhaps running them on an on/off schedule of some sort? They are hooked up to an apex, so any combination of on/off I can do.

At 15W that's max intensity,,, too much for a new/not matured screen, photo-inhabition looks like. You need to reduce intensity, until at least the screen is covered. An easy way to try this is to use some window tinting, just use clear sticky tape to attach temporarily, or even some black plastic or aluminum insect screen will reduce intensity.

Or move the light further away from the screen. Double the distance.
