Lasses Dream Build

[JonasRoman]

question: where is the border between far red and infrared? Do you think also infrared have influence? Most of our light back days contained a lot of far red AND infrared (mhi). The infrared has a heating effect (I think also far red but not sure) which can damage the coral. I think far red also have that effect. In medical therapy far red is used to destroy cells.
When you do your experiment it could be interesting to have a third area with so much red/far red it is possible and see Where(if it is any) the limit is for coral illness. I think (i do not know) there is a limit Where certain amount of this far red Will kill the cell structure and maube the coral.

You wrote a lot of wavelengths > 700 nm - this is only 730-740 nm. It is a monochrome source with peak between 730 and 740 nm. There is only a few more wavelengths in the spectra - see figure I´m sorry if I missunderstand you

Far red of 730 - 740 nm is well tested for terrestrial plants and in use worldwide. The corals shown in post 606 – picture 1 is direct below a source for 730 nm. The one ordered here will probable be used in that way that I put a spot with this LED directly conentrated to on of my hystrix bushes and see what happens. The scientific test will be done in another way.

Thanks. Thats My fault. I expressed unclear. I ment (or guessed) that you explained, but choosed not perfect words for that

Yes I have understood it something like that and it will be very interesting.
The “background light” to this coral with far red, is that from your rgb fixture? Thus, which other wavelength will hit this test-pilot?

amazing tank
do u have aany links to where to buy and use Oxydator ?

From what I know they are more commonly used by people that keep freshwater shrimp so perhaps a shop/website that caters to those people is your best chance of finding one locally.

Lasse, I've just read through your thread and I'm blown away! Tank looks amazing. All the tech part I'm not experienced yet to understand all of but it's very interesting to read about.

I'm just starting to plan my first ever reef tank, it'll be a slow process due to costs and everything but one step at a time and one day I'll be there.

On a side note, I'm from Sweden too but in my research about reefing mostly come in contact with material and reefers from across the Atlantic. In your experience are there any big differences concerning how you maintain or setup a reef tank between Europe and the US for instance? Any general differences in how you approach certain things? Any choices that you have to make differently due to availability etc?

Again, amazing tank! First reef tank I've seen with a BTN background even though I know they have a reef line, and I'm now considering that route too.

Here is the original homepage

@Lasse , the new orphek v4 has included some far red (thus infrared, I suppose that is the same), any comments about that? They got some critics from RB, their opinion was that that should arise a warning flag, but I actually agree with you, that even if we do not know, maybe it is a little too early yo say that it is not good. That light is interesting in that perspective and mimics the natural light more. Maybe they know something more we do not know, as they included that far red in a commercial version already?

Will follow your test with interest.

I'm anxious to see your coral grow. I'm very new, but I have noticed coral adaptation in the wild and in various aquariums, some to the point of being unrecognizable. Very interesting.

 

[Lasse]

Hi @Katrina71

You said that you have notice coral adaption in the wild. Have these observations include birds nest´s

Orpehek 4 include 840 nm. I´m more interested of 730 nm for the moment

By the way is 740nm visible for eye?
Isnt it infrared?

Thank you

There is one large saltwater community in Sweden that you maybe are aware of -www.saltvattensguiden.se

Because nearly all persons in Sweden with an age below 40 are English speaking – we are in some ways influenced of the American way of reef keeping. A couple of years ago RC was the source that inspire many Swedish reefers – today its more R2R references you can see in Swedish reef forums.

The last couple of years – it has been a trend of hypes around different products with origin from the other side of the pool although most of the new methods has a European origin.

In the US – there is still a debate according MH-T5-LED. In Sweden MH -> dead - or at least – deadly wounded for normal aquariums.

US is a much larger market – therefore more specialist – more different corals on the market and it’s also in some way valid for fishes also.

BTN is not very common in Swedish reef tanks either - but It seems that I have inspired some to use it - at least the Slim Line

Its visible for most people. Its interesting also because chlorophyll F has a peak around this wavelenght.

Ok. But chlorophyll F does not exist in corals/zoox?? Or?
Nevertheless very interesting project of yours. There is so much we do not know so I Will follow your results with great interest.

Thanks for What you are doing in this field

Just read an article about that. Seems like due to the fact that chlorophyll F is so newly discovered they don't really know if some corals use it or not. In areas or conditions as where they found the stromatolites it could be plausible.
But it's interesting! Also looking forward to the ongoing results.

 

[Lasse]

A year ago (or so) I saw an article about algae/bacteria using Chlorophyll F inside the skeleton of stony corals. Can´t find it for the moment

30/10 New birdsnest (No 3)

​

The same coral 13/11 (two weeks)

​

Close up - note inside the red lines - The short branching has started!!!

​

Another frag - put in my aquaria 6 weeks ago

first - after 4 weeks

​

After 6 weeks

​

I had 3 more frags put into my aquaria 2 weeks ago but I have been away for a week and some of my hermits did nor agree with me according to the scape - but I save 2 of them - they are placed according to my will again
