Which ati? (1 Viewer)

[bpb]

90 gallon display. Had a few crashes and life happened. LEDs currently over the tank now which is mostly just mixed with a few easy sps.

Wanting to do a full reboot of the tank and go back to all T5HO. Having done t5ho, mh, and LEDs, I was happiest with t5ho and had the best growth and color.

Now I'm torn between the 6x54 watt or the 8x54 watt sunpower. The bulk of what I've read tells me the 8x54 watt unit will be overkill for my 90 gallon. But I am really wanting the 8 bulb to work for two reasons. Firstly I want to be able to include a couple true actinic bulbs. I like how they look and the spectrum they cover, but not at the expense of 1/3 of the bulbs used. Secondly, there is a chance I may upgrade to a 120 gallon in the future and don't want to have to play the light buying game again.

Intended stock will be 99% sps and clams. Mostly acros with maybe a very nice montipora on the overflow box or a stylophora or two in for good measure.

I had considered a Cebu sun fixture as well...but the startup, heat management, and bulb replacement costs are significantly higher and without really much benefit to growth and color

Thoughts?

Honestly, I've ran a 6x54w T5 on a 90/G.

If I did it again, I would not think twice about running 8 bulb fixture.

Two reasons:

1. Better bulb selection!

2. Better coverage!

The 8 bulb dimmable sunpower is 17.4" and a standard 90/g is 18" wide. Perfect fit!

Exactly what he said, no question.

Thanks guys. This same question was cross posted on a few forums and it confirmed my decision. Going with the 8 bulb! Mainly for reasons of bulb selection

Roger that!

The 8 bulb dimmable is bad to the bone. I replaced my LEDs with two of those and only wish I would have chosen them in the first place.

ATI makes a great fixture. The colors you can get out of a ten bulb fixture are unmatched. It's all about the bulb combination. I love playing with different bulbs.

They definitely grow coral very well.

Love that video. The giesemann fixture is sleek, but man oh man it is a lot more expensive than the ati. What gives? Is it just for aesthetics?

Yep. Bulbs are the same wattage. There's been more ATI PowerModule's and SunPower's on Advanced Aquarist ROTM than Giesemann by far. I do believe Giesemann would do a great job growing coral though. It's a sleek fixture that I'd love to test out.

After talking to Chris from CV and Jurgen from Gieseman spectrum of the light is one part of what grows corals.
The trick is to made it last.
That said the Gieseman fixtures are designed for that.
We all know by better cooling from the bulb and ballast the bulbs perform better, the Gieseman fixture has just that little extra as what reflex the price tag too.
Guess what will be hanging on the new build

I definitely trust your words on that diesel. Until the new giesemann matrix fixtures were released, I've heard for years how efficient and powerful ati's cooling is on the sunpower and power modules.

Don't get me wrong the ATI fixtures are awesome as I've two myself.
Gieseman just couldn't stay behind as Gieseman has the better bulb already they had to have a better light fixture too.

ATI has better cooling system than Giesemann right now. More fans and better design. Go look at the video I posted from BRS. It's under the thread that says...why do I run ATI T5's.

Go to 24:40 on video at the end. You can start 2 min before that to get it all.

Here's a question for you sunpower users.

My tank is your run of the mill 90 gallon at 18" deep. I have a fairly tall canopy over it that I would like this fixture to fit inside. I see online dimensions say the fixture is 17.5" wide. Now is that 17.5" at the absolute widest point of the aluminum housing? Or some bulb spacing width measurement. I'm needing to find out if that width is from point to point where the housing comes to the points on the end. That'll make or break which fixture I end up with. Can someone measure theirs and maybe take a pic to confirm it for me?

I'm pretty sure it's point to point. Like outside to outside. I'll confirm for you in the am.

Someone on another local forum confirmed. It's officially too big for my canopy. Options now are to place on top directly, which puts it 12" above the water line, get the 6 bulb fixture which would fit inside the canopy and hang lower, or get a Hamilton Cebu sun which would also fit inside

I would go ATI or Giesemann. Just modify your canopy for it to fit or build a quick DIY canopy. Super easy and fun project. 12" above the water line isn't that bad. In the future, you may want to go lower.

 

[bpb]

I think I may be able to perform minor surgery on my canopy. It looks like I can possibly fix it with a chisel or pry bar and a hammer and maybe not even use any power tools.

I'm probably a 4-5 on a 10 point scale on handiness. Handy enough to know what I would need to build a new canopy, but not handy enough to own those tools or be able to complete the project alone.
