What Giesemann spectra to choose for 96x48x33 sps tank.

jda · Dec 3, 2023

I was just thinking that if weight is an issue and you don't want the T5s, then why not get some MH only pendants from ReefBrite. 8 of them. It is too bad that you likely cannot find 8x of the 14x14 ish Hamiltons.

You can put on Reefbrite XHOs or T5 retros or whatever in between them.

I was looking at it and thinking I could get the blasts locally. However it doesn’t look as good as Giesemann. Tank is in lounge so that’s bit consideration. Spectra is 11kg each as per website. So is the pcc gen2 so I’ll be actually taking some weight of the rack. I have to build something new tho

Hi, I’m decided on Giesemann and currently getting the order sorted with the guys from Germany, they also suggested that 6x 400w spectra 600mm (24inch) would be more than sufficient if mounted in 2 rows of 3 lengthwise. Suggested because shipping 6x small units is much easier than 4x big ones. What do you think?i

That is probably fine. Decide quick once you get them so that you can order 2 more before they don't have them anymore or change the look or something.

They said it will be shipped after holidays, freight volumes decrease and more chance of glass surviving the journey

Hmm, I was curious as to your weight calcs. How "remote" can you put the ballasts?
Your 24" plus if you need to mount the ballasts on the rack come to 6 +4.8Kg (400W ballast).
64.8Kg (142.5lbs approx) total.

Your 4ft would be your 11 plus 4.8Kg

I was thinking to mount them on the cover that sits between tank top and wall.

You going to use some of the Giesemann 400w bulbs? Curious as to what you choose.

Ushio still has 400w in 14k for not too expensive:

MH-S400W/14,000K/E39/T15

400W, 14,000K Aqualite Metal Halide, E39 Mogul Base, T15

It’s gonna come with megachrome crystal I think. Was gonna change to something little more blue. Radium’s looks sold out at most of the places. How’s the ushio as compared to radium? Colour wise

Marine - 12500K - Emulates shallow reef lighting for great growth of coral
Coral - 14500K - Great white coloration focusing on a subtle mix of blue while still providing good growth and fluorescent coloration
Crystal - 17500K - Optically white but gives off peaks of blue and violet to help give the best coloration and growth
Blue - 21000K - Emulates deeper waters with a deep blue spectrum and very little red and yellow light produced

17500K megachrome 400 watt feedback

Is anyone using the Megachrome 17500k crystal bulbs? I have been using Radium 20000k for quite a while and was thinking about getting a few to try out. It will be for an all sps tank. Any feedback would be great.

Is that fixture de or mogul?

Ushio 14k is high output, but is not as blue as Radium 20k. The color is nice, just not like a Radium. If you want a little more blue, then the 14k Ushio probably is not for you.

Ushio makes 20k ?

jda · Dec 11, 2023

Ushio does. They are a Germany bulb maker. They very likely stopped making Aquarium bulbs, but they make bulbs of all other sorts.

The Crystal bulb has a nice blue pop also with a bit of purple. It is nice. It is different than the Radium 20k, but not in a bad or good way... just different.

I think 20k are available to bulk order from somewhere
