    T5 bulb combination- Acropora dominated

    I wanna change up my bulbs. Instead of running bulbs that please my eyes, I figured this time I will try to please my corals and get the best possible growth that I can. Anybody care to discuss their current bulb combination from front to back and why you have chosen it. Would be nice to hear...

    Geisemann Futura vs Illumagic Blaze

    Doss anyone have any experience with these two lights? I’m trying to decide between the two for my new tank build (120gal 48x24x24). Geisemann obviously is the bigger name, but I don’t see any uv diodes in the clusters. Illumagic is lesser known, at least around the Midwest where I live, but...

    Trying to find balance with 4 bulb T5 fixture

    I purchased a used 4 bulb T5 fixture, and look to replace the bulbs soon. It's an aquatic life fixture and I believe it still has the OEM bulbs in it. Its running 1 White, 2 Blues, and 1 Purple bulb. I'm looking to keep softies, and maybe LPS corals in this tank, and I'd like them to grow, and...

    T5 4 bulb par?

    Anyon have a 36" 4 bulb t5 over your reef and happen to have a par meter? I have one 8" over a 40b and was wondering w/o the investment what the #'s are. My rocks are pretty low so probably about 14" from the rocks to the light.

    An honest review of the Giesemann Stellar

    I started my reef journey many moons ago when keeping softies was considered an accomplishment. Over the years I have been amazed by the advances and technology that has become available to us. It is really incredible how far we have come in this hobby. By nature I am a techno-geek and eye...

    Hanging a lighting fixture

    I have just hung a 24" Giesemann MH/T5 lighting fixture from my drywall ceiling, using two 3" long, 3/16" diameter toggle bolts. I believe each bolt is rated to hold 150 lbs and my fixture weighs 25. Unfortunately I wasn't able to hang the fixture using the studs (and the ceiling is...

    Giesemann Aurora 48" for sale

    I'm transitioning an SPS tank to soft corals/anemones and my Giesemann Aurora is overkill. It's the 48" model with 3 85w LEDs and 4 54w T-5s. Easily the best Reef light I've ever owned. The color, shimmer, usability and power are all top notch. Corals grow like weeds. It's all controllable...

    FS: Giesemann Infiniti DE 250w 48" Metal Halide T5 Fixture (custom Polar White)

    Testing the waters a bit. I just found my mint condition Giesemann Infiniti fixture from back when I had an ELOS tank. This is an Infiniti that was custom built by Giesemann for me, in white. Because it was custom, it cost quite a bit more. I realized I had kept it because I thought if I ever...

    Talk Me Into Or Out Of Halides

    I typically don't ask for advice in anything I do. I like to learn on my own merit, whether it be learning from mistakes or getting lucky the first time. With that being said, I have never owned halides before. I currently have a Giesemann Aurora, which is a T5/LED hybrid. The fixture is...

    Giesemann Vervve - Force a "master" into "slave" mode?

    Hello all. I ended up picking up a bunch of Vervve's during BRS's Black Friday sale - waaaay too good of a deal to pass up on. Anyway the way it worked out the Masters were actually cheaper than the slaves, so I bought 4 of those. I am hoping I can force the other masters into slaves instead...
