Modern LED scrubber light

Thanks for the reply

"Any problems getting things from Australia?" Rygh said

It did take 2 weeks but considering the distance(I'm in the USA) and they did just get off the manufacture floor (new bins)

no big deal. I have yet to test the led that I got but I have not heard one bad complaint about this company yet. (no small feat)

Gone all led. Great. You could be proof that led work for SW.

Side notes:

Will be a least 4-6 weeks before my 680 nm Marubeni led come in. My Zillionth revision

http://www.tech-led.com/data/SMB680-1100-I.pdf

I have been somewhat drawn by the high tech t-5's (been finding many advantages) but thats the past led are the future.

If anything I will know what to get, how to setup them up, where to get them, and what to avoid.

Thanks for any help.

Hope so. Interestingly, the seeding seems to have done far more than all the tinkering with wavelengths.
I am wondering if that might be some LED specific thing. Perhaps what grows first changes with LED.
Sure seems like most other builds don't need seeding.

Sacrilege. :o
I still have some T5's on my main tank, and I must admit the huge variety of colors available is rather nice.
But I always forget to replace them on time, and the sudden change in brightness is a big shock to things.
And the expense for bulbs and power is quite annoying.
I am still hoping for a bigger tank. (Working on approval from the wife).
Once that is decided, I will probably go 100% LED there as well.

Quick update:

I had a sudden surge of growth after I seeded, but it has subsided a bit.
It is still doing better than before though. And more importantly, the green hair seems to be winning over
the dense yellow algae. And the yellow stuff seems to grow a bit, then stop.
So seeding was definitely a help.

The other reason in increased growth I found out this week : A fish went missing.
I have a small school of blue-green chromis, and noticed it was a bit smaller than usual.
Carefully counted, and one seems to have died, and probably rotted in some rocks.
Small 2" fish, but still no nitrate spike or anything, which I am happy about.
But does explain the short term increase in growth.
I also had 2 hermit crabs die. So I hope nothing is going wrong. But did water tests, and seems fine.

My annoying bubble algae is looking a bit unhealthy now. Very excited about that. But it is not what I would call dying yet.

I can't see how seeding could possible hurt. Why not try. You aren't introducing a lot of nutrients into the water with a small

amount of algae. Could you introduce something else? Sure. I regularly hide in my crawl space with a foil hat.

Quick update on my setup. Hope you don't mind Rygh

I turned off my 10 watt deep reds just because I was getting some yellow burnt areas.

Could probably increase the flow but this adjustment doesn't cost me money i.e. it is easy to unplug the driver.

So my ledengin warm whites and assortment of rebel blues are lighting the screen nicely.

I am getting good growth, should of probably went with 5 watt versions of the deep red.

Thinking, because I do have a digital aquatics controller, I should maybe try some short off and on times

with the deep reds. Still experimenting. With these results though, with the warm white and blue mix, the

cree 2700 K and 470 -480 blues that I mentioned in a previous post would be a great idea. Fairly cheap too.

Hope this helps and thanks for any help.

How short of a cycle are you thinking?
Have you read anything on trade offs there?
I am running 6/6/6/6 on/off/on/off right now.
Note that I only have about 30W total, so a lot less than you.

Pity about removing the deep reds.
I am convinced that the current Blue + warm_white + deep_red is much
better than the old warm_white + regular_red.

I am a bit adventurous when adding things from the wild.
In fact, when I collected the algae from the bay, I also grabbed some mussels that were
growing in the muck. Threw them in the sump, along with some muck, just for fun.
They seem to be happy, although I doubt they like the temperature.
I really believe that the more complex the biosphere the better.
That said, I am very careful quarantining from the fish store.
Like the doctors office, a good place to catch some nasty diseases.

BTW: I wonder what those govt agents in the black helicopters think of the freaky purple glow from these LED systems.

Thanks for reply

The on off times I am talking about only would apply for the deep reds. (I think they are just are to powerful)

The Digital Aquatics controller comes with a power strip of 4 individual plugins

any one of which can be controlled separately. I might easily start off with a few (10-20) minutes a couple

times a day and see what happens. Aren't led great? Experimenting is half the fun

Side note

I have been very happy with the controller

it has a lot of different upgradeable paths without having a large buy in price $99

bang bang

got a run they are at the door

I have started to run the deep reds for an hour after the scrubber lights are on for a hour.

Great news my discus are showing signs of breeding behavior. wak a wa wa

It's working! It's working!

In two months I have brought back fish from the brink of death to breeding. You can't deny the power of the algae.

Very glad to hear you are having good luck.
Mine is still so-so.

My screens keep getting taken over by this fairly solid yellow algae. The pods don't touch it, and
it seems to out-compete the hair algae. And it only grows to a fairly thin thickness, then stops.
Sounds a lot like the brown/black slime, only yellow and more solid.
Maybe the LED version??
Hard to scrape off as well. Sticks between the screen and the underlying plate, and it is tough stuff.
Cleaning/seeding helps, but I can't do that forever.
As a result, filtering is not so great. Not bad. I get a lot of algae mass every week. But not a full success.

I am trying to clean screen every few days now. Will see.
I might try propping one plate up, and adding more screen, for a mini-vertical section.
Maybe it is a function of the horizontal aspect, and the mesh/plate build.

Also, I have increased feeding quite a bit, including phyto, which my few corals really like.
Unfortunately, the Aptasia like it even more. Argh. Peppermint shrimp time I think.

Yellow is from too high a light/flow ratio. Reduce the light, or increase the flow.

Now I feel like an idiot.
You gave me the same advice a while back, and it helped.
But with the excitement of the new warm-white LEDs I added, I increased the amount of light, but forgot to crank back the overall time.
Then of course, I forgot your advice.
:oops:
Thanks!
