Bro kage, is it ok to tan the aro by the side with just using 1 sunlight tube as compare to those more than 1 tube lighting?
|
Now I think I am going to change my tanning regiment. Had off the top light liao and now planning to on the side one nia. Hope is still not too late.
|
can i use normal light for the tanning?i not sure if my current light can do tanning leh..

bro...i saw a lot of ppl hanging the light like that....but what is the difference between hanging it outside and putting a NAN inside? of course the lighttube is the same. can share? |

Quoting from Arcadia webbie: Ultra violet light of a particular wave band, known as UVB (290-320 nm), is required, and is produced by the Arcadia D3 Reptile lamp. UVB is not present in sufficient quantities in normal full spectrum fluorescent lamps, because the glass absorbs UVB, whereas the D3 Arcadia lamp uses a special glass designed to allow through sufficient yet safe levels of UVB and UVA. |

basically u will need a small night light to balance it off on the other side can liao... its the tendency of some reds to slant their body on one side if they are exposed to extreme ends of lightings on one side of the tank no rocket science technology need to understand this...if I try to punch from the front, u will tend to shift ur face to the back...natural instinctive move nia... **sometimes share still got some idiots like to comments in other threads, I give the thread starter face not to bottle them** btw ur sump whether use jap mats or not is a critical issue, important part is have enuff aeration in the trickle tower part, leave the biohome plus portion dark and shady...not necessary need aeration all out in every compartment...this is not another bakki shower |

now will shift focus to gold and only some reds... sometimes damn sianz also...no appreciation no kick liao...life so boring tonight u anywhere? bubble filter, sand filter, all about playing water...color once genes is gd no need to worry...pity thing is how many can get gd genes? not enuff cash to buy ur type of red so have to come out with "chim chim theories"...u think other ppl will share with u all this hard work?? some throw u a smoke bomb bring u to holland ppl see them as god liao...the more smokey the better...I put clear instructions ppl buay song... |
Since I am going to use another light to balance, can I use a D3 tube instead? Which mean 1 side is a D3 tube in a nan housing and the other side is the hanging light housing. This way, I can tan both side of the aro.

Bro Kage, this is what you mention in the 1st page : Appetite Loss - This again has to do with the way the users acclimatise their reds to the tanning regime...if suddenly intensified lights are shone at them, weak-hearted reds will display stress and lose their appetite altogether. If let say during the 3hrs interval does it mean on and off every 3hrs? If appetite loss, does it mean to stop everthing? Or just leave it until it adapt to it then start to feed again?

I brought this old thread out for discussion.
Chromatophores basically are color pigments responsible for the colors we see on the fish. It can further be sub-divided into xanthophores(yellow), erythrophores (red) and melanophores (black/brown) ..etc Of course there are other classes of chromatophores but this 3 would be our main area of interest. By tanning with UV <380nm, we would expect melanophores pigments dispersion thus darkening of the fish. Here's the spectra absorption chart for xanthophores(yellow) pigments. http://i7.photobucket.com/albums/y27...wPicture10.jpg There is an absorption peak at the 450nm and 475nm. Assuming that we want to bring out the max effectiveness of bringing out the yellow/gold color, we should be tanning the fish with a light source that is peaking between 450-475nm. However, if we were to tan solely with a monochromatic light with a very narrow wavelength at 450-475nm. The fish would appear dark/black as most of the light is being absorbed and not reflected. While this would make a very good tanning light, it would not be a good viewing light as it does not reflect the yellow/gold color we want to see. Take a look at the spectrum chart of the various bulbs produced by ushio. http://i7.photobucket.com/albums/y27...wPicture11.jpg If we were to tan the fish using a 20000K bulb, the tanning effect would be at its maximum but viewing at its worst as there is not enough yellow ~580nm light to be reflected back into our eyes causing the fish to look black. The ideal tanning light would be one that peaks at the max spectra absorption 450-475nm and at the same time peaks at the yellow spectrum. Which in this case would be the 14000K bulb as it gives out less UV (<380nm) thus reducing melanophores activity. My conclusion? I personally feel that tanning with UV while will also bring out the other color pigments(spectra absorption is not an absolute value but a range with max absorption at a certain wavelength), melanophores(black) would be at its max absorption. With black as its dominant color, it would overshadow other color pigments. This might also explain why NAN lights(mainly red spectrum) makes the fish look so red(reflect red light back to our eyes) but does very little for the actual tanning of fish. |
