It's a little blue but not as blue as those led tanks. A height of 10-12"'will cover the 30x30 with no problem.
Thanks so much ! Well if its good enough for you with your experience on a 36 in x 36 in tank, it will be definitely great for me !
My biggest fear is I wont be able to wire it as seen in this thread to a luxcore 250-400 ballast :worried:
Also, do you know if I can attach my reefbrite led strips to it if needed ?
Regards,
Abhishek

Yeah Yeah
I made my cube 32"x32" so I could have at least 250 par at the bottom edges with a single Giesmann Spectra. The coverage is excellent. Here's my tank when it was going well. I'm currently regrowing it (life got in the way). This tank is 32x32x26. Just be sure to use a SE 400 and not the DE 250s. I had the DE fixture, doesn't spread as well as the SE.

Richard , your old 34 gallon and the last one are some of my all time favorite sps tank .
I thought you moved to radions from the spectra ??
Anyways , when you had the spectra - what bulb combo did you run with 400 watt radium ? How often did you change the T5s assuming it's not cooled at all and needs frequent replacement .

Abhishek

Yeah Yeah
Thanks, I had a Giesmann Infinity 250w fixture. It was good on smaller tanks but spread and par is not enough for my liking in this size tank when running a bluer bulb. I like the spectrum of the radium more than any other halide, and in 250w it looks too dim to me from past experiences. Par numbers would be very low on the bottom of my 26" high tank with it. Of course it's doable, but 400w is so much better.
Thanks Abhishek,
I was running radion G4's for 4 months. They're excellent LED's, not a 400w radium, but the best LED alternative I have seen. I am planning a move within the next year and I wanted to sell the radions while they're still desirable. These LED companies shoot us in the foot by upgrading tech so often, at least ecotech does their best to make new technology integrate . But the real reason is because I want the best light possible over my tank for the end of it's life
I'm trying to grow and color as much as possible over the winter. When I complete my move there will be a much larger tank in the picture I'll probably light it with a combo of Radion and T5 with my knowledge at the moment. The t5's in the spectra absolutely suck. The reflector and no active cooling result in very low par. My ATI fixtures put out triple the par with the same bulbs. I'm currently running 2 coral+ and 2 Blue+ trying to get more par and the best growth at the moment. Visually, I always like 2 actinic and kz fiji purple run with the radium. It looks awesome when on alone and compliments the radium very well. I guess I change bulbs around the year mark give or take. The par is low for the t5 in the fixture so it really doesn't make a world of difference.

So basically the T5s are just to add blue to the halide and not really add up any PAR .
It's the 400 watt radium that does the bulk of the workload .
Wondering how good the halide reflector is then in the spectra unit ...
Other option is to run an xm or reeflux 10k bulb to get maximum PAR with 4 actinic ATI T5s to bring out colors in acros ..
I was always a big fan of 10k xm with actinic vhos ...
Regards,
Abhishek
jackson6745
Yeah Yeah
4 blue+ or actinic in the fixture aren't powerful enough to offset the white color of a 10xm, and the AC 10k is weird pink spectrum even with t5s on. Think normal output tubes lol. Seriously, the T5 output sucks in the Giesemann. I don't even know what bulbs are still ion existence, but an aqua connect 14k would be my next choice besides a radium. FWIW the Spectra halide spread better than the Sfiligoi fixture that I had before this, but it's not as good as a full side diamond style reflector that you would retrofit... Those reflectors are absolutely huge though, they must be hidden in a wall or canopy etc.

Jackson6745,
Congrats on the tank, absolutely beautiful. Im back building an sps tank and have a new Spectra with 2x250w radiums. Im undecided on the T5’s was thinking on adding actinics and KZ Fiji Purples, as you mentioned. What is the difference between the last one and ATI Purple+?
The colors of your sps are very nice. Reminded me what halide results look like

Yeah Yeah
Thanks. Unfortunately, after about 1 1/2 years I had a big die off. The tank grew very dense, flow became a problem, corals shading each other became a problem, and my work schedule was the main problem. I'm growing it all out again
. As far as the fiji purple + purple+ I don't see much of a difference, either would be fine.

Glare shield
Glare shield
Has anyone attached a nice looking shield of some sort to eliminate the glare from the MH in the Spectra? I'm catching some glare off the reflector at the moment - my light is 9" above the water and it is really visible when I sit in my easy chair about 5 ' away. I was thinking of attaching a high quality strip of some sort that will compliment the fixture but shield the glare.

Do you have a picture of what that looks like?

Xho strips
Xho strips
Can you show us how you attached your Reefbrite strips to the Giesemann? I just received mine but find the XHO are about a 1/4" longer then then the Giesemann fixture. Plus there is a protruding part (bushing) sticking out on each end for the screw to go.into. I would have to bend the L brackets that come with the Reefbrite to make it work. I'd prefer to have a clean look for this.

I love my Spectra, for me MH/t5 is the only way to grow corals but the limited control stinks. I decided to supplement my Spectra for a bit more light and a lot more control. I really wanted some dimming as well as the color pop of blue LED for evening viewing. So on top of the 2, 250w Radium and 4, ATI Super Actinic I've added 2, ReefBrite XHO Blue and 1, AI Hydra 26 HD.
I know this much light is completely unnecessary and potentially dangerous but I'm really enjoying experimenting with ramping schedules and acclimating my tank to the new lights. I'll never run them all at once at full blast but with them all turned to max they put out more than 1000 PAR at the center of the tank on the water's surface.

HA - I may consider something temporary that is similar. Of course an expensive solution might be to add a reef brite across the front but I already have lighting overkill on this tank.
