New BLV 14k lights too strong?

[tineng]

actually i love the new BLK 14k lights.....however, after talking to people, i realise that other then me, 2 other reefers also faces bleeching issues with some of their corals when switching to the new 14k lamp.....

so just let to hear from other reefers if they have enocuntered the problems and possible some of the actions taken by reefers here to handle this issue....

[blueheaven]

Yeah I am also very interested to know more.

How is it working for you scarab?

[dt8666]

I only run it a day and found it much yellowish as comparing to my current 20K. Not sure if it will be too strong.

I also read some other reefer claim the same yellowish effect. could it be not enough run in time?

[weileong]

Maybe your eyes already tuned for the 20kk so it takes time for your eyes to tuned back to the new BLV14kk.

I saw the BLV14kk 250W DE fired up at ML and it is very white.

The 14kk might be brighter so that might cause the acros to bleach if you didn't reduce the lighting hrs or move the lights higher. This is the same when you change out old bulbs.

[AlfaRomeo]

Yup, always shorten the photoperiod or raise the lights when doing a bulb change and then slowly increase the photoperiod or lower the lights every week or so until its back to normal.

If not, the acros will bleach in response to the sudden increase in intensity.

[tineng]

yeah....actually was plaining to moved my up further before changing the bulb.....but was too lazy......

interestingly enough a pink digita that was previously under a 10kk BLV 250w (5 month old)....when moved under the 150w 14kk blv bulb also bleech!!!!

I wonder if bleeching can be caused by a suden change in color temp??? or maybe high time i should change my BLV 10kk bulb....

[loster]

may be it is time to go down ML and pay a visit. didn't know henry changed his bulb to BLV 14kk.

i tried it for about 3 weeks and it bleeched both my lps on the bottom and sps on top for those who light looks very yellowish (i have 10kk and my 10kk don't looks yellowish as this), it may be have to do with the ballast. especailly those who run e-ballast. after i have change my bulb to another MH which run with another ballast, it is so much whiter on the top (very white) but at the bottom of my tank is greenish.

may be i go down to ML and have a good look at the henry tank to see the different.

[Travy]

I using the BLV 14k 150w.

SO far am very pleased with the spec. Using a 10k b4 and i can say this new bulb is indeed much whiter.

LPS doing fine so far. Light is abt 4" from the surface of the water.

[calvinci]

I change 2 of my BLV 10KK to 14KK recently, and lower the light some more. No bleeching, color is definately very white, SPS flourence more now.

[loster]

can post some picture with your lights "on"? i am still looking for one more bulb

[Guinness]

whiter???? maybe my eyes gone funny.......

My tank looks strangely bluey...... I will report back after about 2weeks of using....

[yus75]

[weileong]

You will love the color and how your sps appears under it.

[lyz77]

I'm using a single BLV400W(14K) and I notice during the initial fire, it's a bit yellowish and after a while, it turn to white. But not sure it's due to individual eyes or wht as I still feels that it's slightly yellowish rather then bluish!

[weileong]

The BLV14kk is whiteish, don't think anyone said it is blueish

[Fauna Marin]

Hi Lyz 77

We use the new BLV 14.000 K a lot in Germany I never heard and see that it was too strong , also i can never see that is to yellowshit it looks more strong white with a little bit blue

Which ballast you use ?

Greetings

Claude

[speakerphone]

Fauna marin, since you are the expert. advise me which brand t5 is the best. can t5 replace MH?

[Fauna Marin]

HI

I think the best is the mix of MH and T5

There are a lot of good T5 Brands on the market so it depends whats in your tank and what you like for your eyes.

MH has some advantage and also T5

What you have in your tank ?

greetings Claude

I intend to keep both lsp and sps, still cycling my tank.My tank 5 by 2 by 2.5ht

How many T5 or Mh I need. what kelvin should I use? since you are from germany, can I order german stuff from you such as t5 tube?

Good brand such as? how do you comment about ati,d&d? and lately some issue about aquascience 20% better then ati?

Thanks

[Fauna Marin]

HI :-)

I think that is a tank with 1.5 m x 0.6 m x 0.7 m

So we use here 2 x 250 or 400 Watt MH with the Colors 10.000 to 14.000 K

The Kelvin is a little bit bad but the most selling brands in germany are

BLV 10 or 14 K than Giesemann Megachrome coral or Marine then AB 13.000 K ( is more yellowish and then UltraNova 12.500K quite white and very bright !

and then we use 4 x 80 Watt T5 also different brands the most will use Giesemann JBL Arcadia some internet guys ATI and also a lot try the new aquascience

I will do normaly 2 x white and 2 x blue

If you want to use only T5 then you take minimum 6 better 8 Tubes or 10

and mix it 75 % white and 25 % blue

In germany they do a big test about the new tubes this article will come in the next days There you can read all ;-)
