[BBQHILLBILLY]

I noticed with my coral like to grow more with blue than the white LEDs. Im at 12 hrs blue LEDs and Red and 6hrs White. Thats my sps frags, softies, and LPS.

[Big_Pun]

a blue light and a white light putting out same par shouldnt change growth rate. kinda seems simple. its the why i run ati blue plus as it puts out more par than some other white bulbs.

what high light level coral are you basing this off?

[BBQHILLBILLY]

I agree. I observed that I got better growth rate with 12hr blue LEDs compared to 12hr white LEDs. Looks better too.:shades:

I know its just a small amount. I sold most everything to help with funds transferring to the other tank. So Im limited.

[350gt]

I just posted cause I thought the 6500-10k look was better for growth... And heard the 20k look was mainly for preference...

[BBQHILLBILLY]

I saw noticable improvement with Kryptonite, Bubble gum monster, pagoda, frogspawn, yumas, green toadstool, fire and ice, and a few others better growth under blue LEDs with a little white

[rrasco]

It's not all about PAR, the wavelength of light matters as well. It also depends on what your lighting source is, T5 and MH have a broader spectrum of wavelengths while LEDs are much more narrow, that's why you see the various colors in LED fixtures; to account for missing wavelengths. "Blues" can range in wavelengths from 450-470nm, while whites have peaks in these ranges as well as in the 550nm range. It is widely believed that corals use more wavelengths in the blue ranges to begin with, so that would support this theory. That does not go to say the other wavelengths are not important. There is also the fact that wavelengths in the blue range penetrate water deeper than the longer wavelengths as well, so that is another variable.

[BBQHILLBILLY]

Thats pretty good there Rrasco. I thought they were stretching out. I dbled my bambams from 2 to more than 6 in 1 week.
I narrowed my whites to 6 hrs to cut down on unwanted algae and the blues rocked the house. Coral loved it.
My blasto doubled, the list goes on . . .

[Sherita]

Following along on this one for sure.

I've always wondered if it would be possible to grow corals under 6500k t5ho growlight bulbs. They are supposed to simulate daylight........corals like daylight, so it makes sense to me.

I don't run a lot of blue in my tanks, and I get crazy growth.

[rrasco]

This is the spectral output for a royal blue LED, peaks around 452-455nm. Notice how narrow the wavelength is.

18877

This is a "6500K" white LED. Notice it has peaks in the same range as the royal blue, but also has a peak in the 500-600nm (green/yellow/orange) range.

18875
This is a "10000K" LED. It is very similar to the 6500K, but the peak at 550nm is lower. The lower output in these wavelengths is what makes the color look "cooler" and more blue. The 6500K is warmer because it has more output in the 550nm range, thus it it less blue than a higher kelvin emitter.

18876
You're seeing red LEDs in fixtures because they are around 660nm. This satisfies chlorophyll A and B's needs for the longer wavelengths.

[Big_Pun]

blah blah blah lets see some pics of actual coral growth, led guys are kinda shy about coral pics. but they love pics of the light fixtures lol!

Lmbo.....

[ramsey]

I can't tell if you're joking or not but I can find tons of videos/pictures of people getting awesome growth results under LEDs. Here's one that'll make your jaw drop:

http://bit.ly/XUaWel

Whether they'll grow coral better than MH is a valid argument but for lazy people like me that don't like to change bulbs every six months and like fancy gadgets (like dimming, thunderstorms, etc.), they're perfect. But hey Chris, you can keep hating on LEDs all you want. BTW, I have an under gravel filter that I'll sell you dirt cheap! I kid, I kid! :)

That's interesting about the bluer spectrums and growth. I wonder if you could grow corals under only bluer spectrums with any success? If so, it might be a useful way to get rid of nuisance algae. Run only in the blue spectrum until the algae is gone. Wouldn't algae need light in the lower frequencies to grow (e.g. A redder spectrum)? I have a few 20G's sitting in my garage, maybe I should test and see. :o

The pink BN doesn't grow very well for me, not like the green, but under led it seems to do well enough.

kinda joking but around here people are shy......also allan would you say that this tank is a little more stable than the last one, that also helps. hate is such a strong word Ramsey, when my light craps out i may swap to led's by that time they should be at "PAR" with MH lol. im just waiting for technology to evolve a lil more, but its getting there.

[allan]

Uh... by stable do you mean that little swing I had there at the end of the old tank? I will say that this tank is off to a great start due to me making 90% new water for it.

That being said, I've been growing Bird's Nest for the last four years, under T5, MH, and now LED. I've had good growth under all three, but this is the first time I've noticed growth over a five day period... and such growth in less than a month.

It's not a statement that LEDs is superior to the other two modalities, only that LED seems to be pulling its weight pretty well. I just happened to have weekly photos for the BN, but I'm noticing similar growth with the Stuber, Red Planet, and Bonsai... not as quickly, but the mass produced by the other three is somewhat greater than the mass required to demonstrate growth in a BN.

I know you're joking, Chris... I just happened to have those two photos, and the time to turn on my DT lights for a moment this morning to snap the third photo.

You've probably not seen my tanks over the years, but I've grown some monster colonies of Green BN, Stuber, and RP. This is the largest I've ever gotten the Pink BN, and part of the reason is something that I've been doing for the last 10 months... not the last month. That colony wasn't born after I got this tank set up.

[Big_Pun]

i have that same b-nest i got from you and it grows like a weed in my tanks, ive had it since the 65 so it been under mh, then just t5, now mh & t5. i noticed the same thing when i swapped tanks some explosive growth, but since march my tank has been doing very well. Leds have the power and the spectrum is getting so much better, just something i dunno, fake looking about the individual colors my eye doesnt like, or used to.

[allan]

You've swam in a coral reef at some point... all of our tanks look fake to the real thing.

Bearing that in mind, it's all about (for me anyway) tweaking the coloration so that what you're seeing is awesome. Don't get me wrong, I like all three modalities, but so far the reduction in heat (MH) and reduction in replacment cost (T5, at the very least having to change them out so often) has made LED a clear forerunner.

I think you're absolutely correct that it's going to get better, and I wish I had the scratch for the vega systems, but right now I'm very pleased with what I've got. In another two years when they're replacing the Vega with something else I'll probably upgrade to the vega. Let the market saturate for a minute.

In another two years (personal assumption) the biggest fan of LEDs will probably be you. :) Of course we may have another modality by then that's superior to the LED.

[allan]

i have that same b-nest i got from you and it grows like a weed in my tanks.

You must trim the dog mess out of it. Bear in mind that over the course of a year that frag should be the size of a football.

[350gt]

It's just a matter of time for Chris..... Lol he knows it
it then he will be bashing the next technology.....


Its okay Chris, it's what all old ppl do...

[350gt]

So who's going to give me a frag of their weeds??

[allan]

Not me, not after that old comment. :)

I'm fixing to have to thin out the pink bird's nest. Haven't gotten around to it yet.

[Big_Pun]

when you come by, just bring your shades :shades:


whatever i get bashed for my MH and bio pellets and snake oil Dr Tims i think i stay up to date with my tank

I think the problem you would run into with trying to eliminate algae that way, is that zooxanthellae are molecularly very similar to other algae. They are a single cell organism that relies on photosynthesis to feed chlorophyll. Chlorophyll requires some of the higher wavelengths to thrive as well, so you may do more harm than good removing those wavelengths. Zooxanthellae are actually dinoflagellates.

Was talking about Chris bashing newer technologies....

im here for Chris.... Sort of therapy. You have to read some of our texts... Lol

[350gt]

Allan I'm glad someone like you made the jump....

Really hoping it works out... I made the jump but still consider myself a noob in this hobby...

im sure if Chris made the jump, he would make it work..... And he will love it like all his "new stuff"

[Big_Pun]

after my net module fiasco im done with technology for a while!

[allan]

Tony, let me tell you. I am still a noob. I don't think anyone can think of themselves as experienced without at least 6-8 years in the hobby. I've only been doing it for four years, and I'm still learning the process.

[allan]

after my net module fiasco im done with technology for a while!

What happened?

[350gt]

You think your grumpy now... Wait till u really fall behind... LoL did u figure it out?

[Big_Pun]

What happened?

Chris plus networking do not mix.....

kinda i cant get it to work on my phone just on my comp....i gave up on port fowarding, now some of my settings where screwed up need to go back and set them. :thumbs_down:

[FireWater]

I have lots of experience and still learn something new everyday. There is always abetter way to do anything.
I went from MH for about 4 months to T5 when they became the craze and then settled in with LED. They all have their place, but I prefer my LED now. Tony's tank was looking good when I picked up my berghia the other day. Allan's tank is coming along nicely and he saw what my tank looked like under all LED. I would like to think it was my mad skills that persuaded Allan to make the switch, but in reality we all like what we like.

With all the reading I have done recently I noticed that light in the green spectrum is what most say will grow the nuisance algae and w/out good water quality red will support cyano.

Maybe have better luck with a drink in your hand and BBQ in your belly...always seems to help.

[allan]

Kind of bites that you didn't have much luck with the net module. I wanted to get a review from you before I thought about getting one for my RKE.

Sounds like he just had a port forwarding issue. Easy to fix.

Allan if you ever need a demo, your welcome to stop by.....


Once Chris gets his going he will like it...

[allan]

I think the one reason I hesitated on picking up the net module is that I don't have a CATV access point in that room.

[rrasco]

CATV? Cable TV? Cat5?

Running wires is easy :)

[allan]

I have the fiber optic lines, but it's still coaxle cable for the tv. CatV... Do they call it cat5? I've always spelled it catV.

I think I have the line in there, but gvtc would only activate one line. If I could activate the others that would be great.

I have a spool of catV cable in my garage if I need to run a line.

[rrasco]

No, cat5 is ethernet, coax is catv. I just wasn't sure what you originally meant. If you have a router/switch, you would run cat5 to it from the netmodule. Unless it uses coax for some odd reason. You could always go wireless too.

[350gt]

Add a http://www.netgear.com/home/products/wireless-range-extenders/WN2500RP.aspx

thats the model I added and it also extended my wifi to my sons room so he has a better reception now... Much easier than running cable..

[Big_Pun]

I like it just only works on my laptop... port forwarding is foreign to me like freshwater tanks (in my head that's a swimming pool) lol

[Big_Pun]

I have a wireless bridge like gaming ones or for the smart tv's

[allan]

So that device, I wouldn't need a cat 5 outlet, or would I? I could really use some more coverage in my house. I have the router in one of the upstair rooms, and connection downstairs is spastic at times.

That and my television doesn't receive the signal all that well. Would I be able to activate some of the other cat 5 outlets in my house for hard line hook ups?

[rrasco]

Looks like it is a repeater (signal booster, extender, etc). It would need to be able to receive a decent signal from your current wireless access point and relay it from there. If you get a good signal where the net module is going, you would be able to receive that signal via this device, connect your net module with a physical cable to it, and improve your downstairs wifi at the same time.

[350gt]

Ya Chris how did you hook it up after all? Which bridge are you using?


allan, the extender I am using wont need a cable from your existing router... But it would need at least a okay signal and it will boost your signal downstairs.. It has 4 ports as well so you can hook up the net module to it or any other device that's close to it...

[allan]

Yeah, I don't have a good signal down in that room. I have a repeater in the kitchen that doesn't seem to be working very well.

[350gt]

How old is your router?

[allan]

Well, since I've replaced it three times... maybe a little over a year? Speaking of which, I still have the last one which probably works just fine. The router itself works, just spotty coverage downstairs. My TV has a hard time playing 1080p wireless.

[350gt]

I believe there is a way to use a old router as a extender or repeater....


might be less of a head ache to just run some cables though..

[allan]

The entire house is wired for Internet... for some reason I was only given one activation and I chose that room. Isn't there a way to send that signal back over the ground wire of an outlet and pick it up elsewhere in the house?

Or activate the other outlets in the house?

[rrasco]

'One activation' doesn't sound right. They may have activated one modem/router, which is right, but from there you build your network through switches and/or wireless. You can use the existing wiring, depending on where they go. Is there a central wiring panel? If they are wired back to somewhere you can connect to your existing network then, yes, that's pretty easy. Alternately there are other solutions that use the existing copper in power outlets, but I don't have any experience with those.

As a general rule, I don't trust wifi. It works if you have a laptop or mobile device with occasional requests, but for gaming or video playback I wouldn't rely on it.

[350gt]

WIFI works great in our house, although it may bot be as big as others... My sons xbox is on the furthest end of the house from the router, he gets netflix and plays call of duty and mine craft online with no issues.

I wouldn't use the power outlet method... i would send a cable to the other side of the house if I had too.

The extender was a gamble for me, before adding it he got maybe one or 2 bars on his xbox. I was turned off by ppls reviews and put it off for awhile, well until I bought my net module...lol Getting it hooked up was a breeze, IDK why ppl online complain, but it was simple even on a MAC.... Now he has a constant 3 or 4 bars and no hiccups yet....

[rrasco]

I wouldn't do the power outlet method either. LOL

[350gt]

rrasco this is the like the device I was talking about...

http://gizmodo.com/5626680/netgear-debuts-first-powerline-wireless-n-extender


seems like a waste to me....

[rrasco]

Never seen that before, not a wireless version anyways. Interesting. I've run enough drops in my life, another one won't kill me.

[350gt]

this is my router.... http://www.bestbuy.com/site/NETGEAR+-+Wireless-AC+Gigabit+Router+with+4-Port+Ethernet+Switch/5400765.p;jsessionid=E0E4B3E3835505FA7002864EC1DDA 317.bbolsp-app01-36?id=1218642235468&skuId=5400765&st=netgear&cp=1&lp=9

I love the new netgear interface for iPhone and droids... makes repairing your network a breeze through your phone... also get to see who's on your network.....
