Spend the whole if yesterday fixing up the MH light that my cousin brought for me at $150 each.

[Dinosaur]

150 watt electronic ballast

[Phang]

Dino, Do they have e ballast in 250 and 400W versions???

[Dinosaur]

The underside

[Dinosaur]

Pulling the wire ......

[Dinosaur]

Work completed ........ . Total cost = $300 + $6 of wire for 10 m.

Okie, there comes the problem ...........

1) As you observe, the light tilted to one side due to the weight of the ballast. Try to move the ballst to get a centroid but cannot becuase it has a rounded top. which restrct the movement. Any solution?

2) The bulb he bought for me is a double headed Philips MHN-TD Pro. Very yellowish.

Understand that Iwaki is the most chosen brand for Marine hobbiest. Should get the 10,000k or for 20,000k so that the color of the coral can be seen? And where can I get it?

Thanks

Hmmmm Iwaki???? you mean Iwasaki......

Well, the Saki ray can definitely enlighten........

Do you have the understanding that the 6500k is very,very yellow.....and you will need lots....really lots of actinics to balance it up.......

another alt would be the 20kk bulbs.... for that, you need to consult Barracuda or rrobert... they are currently using them.....

And the 6500k come only in SE, but the 20kks in DE and SE......

Any more enlightening required????

BTW, the 20kks looks very good....IMO, blusih white.real pleasant to the eyes.... only thing is that theres no record of the spectrum output and PAR of the bulb...

Maybe you can ask EYE for some specs......

Thanks will check woth them on that.

Btw, what do you mean by SE & DE

Thanks

[Phang]

SE = single ended

DE = double ended....

Thanks for sharing this lobang...... really helps.

Dino...

Nice pendants you got there!

Did you remove the glass covers or get them replaced with clear ones? Your existing ones look like frosted glass and it diffuses the light a LOT!!! You have to get tempered glass replacements or anti-UV glass as DE bulbs need UV protection or your corals will bleach!

Those are DE bulbs right? Should be coz they are smaller compared to SE.

Need to add that the light spread doesn't seem too great. Can you replace with a broader bell pendant?

Try aligning the DE bulb with the ends perpendicular to the tank's length as both ends do not emit light and may cast shadows.

Thank AT,

DE bleach coral! Oh shit !

Yes, mine is De bulb.

Where can I find anti - UV glass pls, I mean customised one.

You might be interested to pm AGM65.

Spoke to him last night regarding MH.

told me he got his from Kelantan lane and its suppose to be UV proof....

Dino,

I just bought 2 X 150W SE 20K Iwasaki from EYE. Colour is very nice bluish white. I simply mount them on a plank and place it on the canopy of my tank. Very cheap. However, the ballast I got is magnetic. I paid about $360.

[Achilles Tang]

You got the 20k sakis? Interesting... show us a pix of your tank after the burn-in period, okie?

I hope you know that you won't see much coral growth as 20k lamps have very low par even at 400watts comparatively to lower temp bulbs.

That means acros and some sps corals cannot be kept long term as they are more light-demanding.

[Chris]

Thanks for concern AT,

my tank is not a SPS or acro reef. Mine is a softie and mushie with some star polyps, branches and 2 clams. The MH is more for viewing and to add a little more than my present PL...so after much deliberation decided on 150W 20K sakis.

[mv3i]

just curious ...

out of this few

sakis 10k

aqualine 10k

venture 10k

which bulb is more bluish ??? such that i do not really need actinic supplement ??

or any other bulb that you guys can recommend ??

Hi Chris

No prob.. but I noted that you said you have clams... they are light-loving creatures... and you should place them right at the water surface (as near as you can).

[Chris]

I put them high up now with PL but feel changing to MH would be better. Will keep them high up after changing to 150W MH. My tank is 48x24x24.

Thanks AT

There is no iwasaki 10k (only 6500, 20k & 50k)

Venture bulbs not very sure.... are they even selling in SG?

BLV is more white with a tinge of blue

Aqualine is more blue than BLV.

Actinics are high in the violet peaks, 10k is weak in that, so you need actinic supplementation.

But 6500k is full spectrum, so violet is well provided, however our human eye will see a lot of the greenish yellow spectrum.

[BarraCudaTM]

any tell-tale signs of low PAR lightings?

I got my marco algae growing so fast that they give tonnes of oxygen bubbles in the afternoon .. making my tank look cloudy

And how long does a green acropora take to bleach? I got a acropora frag that is brown when out of water and slight green when under the lights
