Next bulb, Giesemann 14.5K?

fisheebill · #1 12/16/2007, 09:41 PM

I am stuck on which bulb to get.
What does everyone think of the 14.5 MegaChrome?

I have 2 blue+ and 2 superactinics for suppliments.

I just want great color, growth can be slow.

Thanks for the help,
Bill

Well not running that bulb, but I am running the Megachrome Coral ,day 2, it is a 13k, very slight yellow tinge, I think you would be happy with the 14.5. I like the look with 2 superactinics, and 2 50/50 bulbs that I am running now. And the corals really perked up already, I was running the phoenix before and growth was very poor. This is the 4th DE I have tried and my favorite so far.

I use it on my SPS tank. Good growth, nice color.

neelix, I wonder if the yellow tinge will be gone soon. I have the 12K Megachrome and it doesn't seem to have a yellow tinge. I might like the 13K.
Could you give me an update in a week or so?

snorvich, thanks for the input. Are you running any suppliments with it?

I have them on my 180. They give good color and growth.

Thanks erendon.
I think this will be my next bulb.

I use the Giesemann Coral alone, it is BRIGHT, and a nice purpley-white after it burns in. No actinics needed for me.

The usual burn in time 100 hours?

Just curious since I already like it and if it becomes a bit more blue it will be fantastic!

That sounds about right. BTW the Megachrome Coral is Giesemann's 14.5K bulb.

My favorite bulb so far and I prefer them much more than Phoenix which washes a lot of colors out IME.

I have a Maristar fixture and also dont feel that they need supplementing with actinics so I run them with a Blue+ and an AquaSun which gives my tank more light. I have mostly SPS and clams so try to maximize the PAR, not that these bulbs are weak by any means. I run the G-man on an SLS Bluewave III HQI ballast and feel they are the perfect color for me. YMMV.

I have been running these 14.5 on the ends of my 180 for about 6 months now with aqua medic fixtures. I have tried the 12 & 13 and IMO the 14.5 are better but thinking of going Phoenix next time for more blue. In the center I run dual 400 and tried my first radium today and like it.

I have the Gman Coral 250 HQI and love them. Great bulb and I do use 4 T5 (54watt) pure atinic's

Thanks everyone!

does anyone run the 150W version of this bulb, and if so, are the opinions and results the same as the 250?

fisheebill · #16 12/20/2007, 01:15 AM

I figure the 150 should be the same as the 250.
Or could I be wrong?

smatter · #17 12/20/2007, 04:59 PM

Going to the Phoenix is a downgrade IMO.

fisheebill · #18 12/29/2007, 12:24 AM

Got the MegaChrome Coral today.
I will throw up some pics just for the heck of it.
Maybe one early and one after 100+ hours.

Can you please post a pic with just the MH only. Thanks

fisheebill · #20 12/29/2007, 12:57 AM

Sure will

fisheebill · #21 01/01/2008, 11:54 PM

Here is a pic with the t5's off.
I am going to try to get a better pic after 100+ hours.

mile sq. reefer · #22 01/02/2008, 01:14 AM

Thanks fisheebill, but can you please post a pic of how it, MH only, looks lighting the tank. Hard to get a feel for the bulb with a picture of the fixture and lamp.

fisheebill · #23 01/02/2008, 08:52 AM

No problem
