WHy Coralvue Cesar? Just curious.

If I were to pick the two, I'd pick the XM's.

Let me know where you are ordering from , maybe I can order with you and split shipping. I need another XM10k.

and here is what im using right now... SunAquatics 10K

Also im using M59 and might not be able to go Hamilton 14K.
Also Im basing my decision from JB NY's 250 watt data on standard PFO... since we still dont have coralvuew data from Sanjay...

And also consistent with "Redeyereef" observations from his new Licor light meter...

The 400 XM20ks will turn whiter after burn in on standard M59 magnetic/coil ballast.

Where are you ordering from, and if you haven't ordered yet...let me know.

if you go with Custom Aquatics don't forget to use the 5% off coupon for Reef Frontiers. I don't think Marine Depot offers that. All my business has went to Custom Aquatics lately.

How do i use the 5%off... Marine depot has free shipping on 175 purchase... almost the same...

Cesar - just go to the Sponsors page and scoll down to Custom Aquatics and click on the link. It should add the Coupon automatically to your shopping cart. I don't remember what the code was....

and what is growth like with the 20k's? quite a few threads/articles i've read say that with 20k's you'll notice a drop off in growth.

20K bulbs are too blue for me IMO. I've been told SPS growth rates do slow down, but that can be a good thing though. :)

Thats true.... but considering that I am coming from a 175 watt... that is still a big change...

Also, 20k is really blue thats why I am going Coralvue because its more white than the rest of the 20k's.... it looks 14k's...

About the growth... thats ok... I dont intend to make them really grow that fast...I want to figure out first why my corals are not the same colors where they came from and with comparison with other tanks... most of them are brown.... :( Also remember... a lot of people are already using 20k's...

Fragman is using 20k's on his frag tank with white pc's.
Salsaking I believe is using Coralvue 20k's. If you havent seen it in person, I highly recommend it...

Props is using Sunaquatic 14k's which is like Radiums and a lot dimmer than coralvue 20k's....

that's a good point! coloration of the corals. something i'm somewhat dealing with right now. i think we talked about this at the meeting.

i have one coral that is supposed to be purple and the new growth is purple but the rest is a whitish-brown. i've moved it around the tank and up high trying to get it to color but so far no luck. the rest of my corals and their colors look fine.

i'm running 250w 10k XM's with 2x110 Super Blue VHO's. You'd think I'd have a somewhat well balanced color of corals.

Let me know how the color of your corals change with the new lighting. I'm definitely interested. When I change my bulbs next time I may go with 20k's but I'm having such amazing growth with XM 10k's it'd be hard for me to change.

I have a 250watt de xm 20k and I know that it is different from the 400w 20k se, but I can't say enough good things abou this bulb. I do know that the picture shown with the xm 20k is not accurate imo. It is tough for a camera to pick up the true look of the 20k with out white balance played with or changes made in photoshop. IMO its not too white or too blue, and the color of my corals shows it. Good luck with your decision. Also to add, I have not used the Coralvue so I have a biased opinion I guess.

Shoreliner...I hope you can post some pics...

Shoreliner11
12-06-2004, 02:20 PM
Sure. Being that the color balance is off on my camera I adjust the color balance in photoshop to be imo as close in to the real thing. With that said the pic is a little dark cause of the angle with the light reflecting sand. I'll see if I can get another. Here's a pic.

mattseattle
12-06-2004, 02:21 PM
now that is the color i want my tank to be. guess i'll try the 20k XM's next time.

how is your growth?

Shoreliner11
12-06-2004, 02:26 PM
Here's another pic. I think the color is about the same. Now keep in mind these are 250w de 20k xm's run on an hqi ballast and not the mogul based 400 watt xm. I would imagine their color to be very similar. Also, I hear that running a 20k on an hqi ballast for mogul based helps a lot with the whiteness of the bulb.

Hey Matt, shore is referring to the XM's DE.... and not SE's

Shoreliner11

My growth is good. I made a stupid mistake a couple months ago and lost all of my sps and much of my lps declined heavily. They are making a comeback but the sps frags/small colonies I have now show great color. Which is why I wanted the bulb in the first place. Just to make sure Cesar, are you using any actinic along with the bulb? If so, I would definately go with the coralvue instead cause I believe that would be too blue. I hope the color is not that different in the se ended but again I haven't seen the se

mattseattle

Cesar - would the color be that different in the DE version versus the SE?
