color spectums in the metal halides.

reefman420 · 08-27-2007, 10:55 PM

hey i bought a used light fixture off of ebay.well one of the lights is more of a lighter color and the other one is blue as a actinic.does it matter for now.their both 175w with 10,000 k.and i only have one frag with 3 mushrooms
which side should i put him on if it really matters for know!!(have to order bulbs from aquatraders on friday)

CATALYST · 08-27-2007, 11:06 PM

One could be older than the other. I have a post where I just got my MH and it was sooo blue. It is turning whiter with time.

reefman420 · 08-27-2007, 11:09 PM

ya so i should just buy 2 new ones since i bought it used?

CATALYST · 08-27-2007, 11:13 PM

Couldn't hurt...may save shipping. I would space out putting them in and not do them at the same time...Just because you don't know how old they are. Don't want to stress your critters either.

reefman420 · 08-27-2007, 11:15 PM

how long should i wait?i only have one mushroom right now

CATALYST · 08-27-2007, 11:19 PM

You could put them both in and just increase the amount of time they are on little by little.
Then you know when to change them for sure next time.

MH coe in several Spectrum 6,500K being the yellowest, 10,000K next, 14,000K, the 20,000K which is really blue the same goes for growth fastest is the yellowest, bluest is the slowest

reefman420 · 08-29-2007, 01:18 PM

so the yellow light groes corals better

AQTCJAK · 08-29-2007, 01:24 PM

I wouldnt say better faster yes the trick is to grow under 6,500K the move to the 20,000K to color up

reefman420 · 08-29-2007, 01:34 PM

well i bought a mushroom frag the other day and put it under the yellower side.he seems to love it.i was scared after i bought the lights..he gave me replacement bulbs,but i dont think their right.we switched them around and they didnt fire up...we tried useing the brightest old bulb and a new one..only the old one fired up..what gives i guess ill just buy bulbs from the manufacturer

AQTCJAK · 08-29-2007, 02:18 PM

This is a good comparison between 10,000K HQI & a 13,000K LED & 20,000K LED

BigAl07 · 08-29-2007, 02:35 PM

Wow! Now that's BRIGHT! wonder what the neighbors would say to that 20,000K unit. It's been said jokingly that my living room glow looks like I have a nuclear power plant in the house at night. Our home is on a hill with lots of windows and at night with just the tank lights on (only 130w PC's) it does give off an eery glow from afar

Great comparison Jack. Thank you

Allen

Boomer · 08-29-2007, 05:01 PM

It is really not the K but the PPDF that has the greatest effect on growth. The K is more of a coral coloring issue. And most high K bulbs have less output in general. And K has very little effect on coral growth. To this day, since I introduced it almost 20 years ago, nothing is close to a Iwasaki 6,500 K 400 W MH. All one has to do is look at any of Sanjay's bulb tests.

BigAl07 · 08-29-2007, 05:13 PM

Boomer what makes Iwasaki 6,500 K 400 W MH so potent other thank it's 400w? I want to get the most from the light but also want the corals to get the most efficient spectrum they can...

Allen

Boomer · 08-29-2007, 05:19 PM

It is the way it is designed and ballasted. First, it is not a true MH but a mod MV and runs on a MV ballast. If you took two 400 W MH, from different companies, there will be little difference but along side a Iwasaki you will see a big difference.
