• Who has what MG?

  • Allison

Good evening everyone. Can you tell me what MH bulbs you are using (how many kelvins), what color shades they produce, and how the corals respond? I would appreciate any advice and experience! I am planning a light setup with 3 MH 250 watts + 4 T5 at 80 watts for an aquarium measuring 1800*700*600 mm, a mixed reef with a focus on SPS and LPS! Merry Christmas to all! Wishing you all the best and only in bulk!

150W Aqua Medic aqualine 10000. Very bright warm light. MEGACHROME coral. Very bright white (truly, chrome) light. The lamps shine excellently, like a bright sunny day in Egypt. Both completely overpower actinics, 48W.

The net volume is about 700 liters, and the desired light is for 1100 liters. It seems to me that it will be too much. I have two 150W metal halide lamps (14000K) at a distance of 25 cm from the water, and they heat the water quite well, while three 250W would be excessive. Two 150W will be enough, as one covers an area of one meter by one meter. With three 250W, the fish's eyes would pop out, and the invertebrates would bury themselves in the sand. They also need to be placed at least 0.5 meters above the water, which would create quite a glare in the room.

Off-topic. No, Yoda's topic is about T5 and MH, specifically about their replacement. There are no questions regarding PL lamps. Regarding K-M.A. (marine aquarium) 13, and Gismann (chrome) 14, if I remember correctly. (+50%), but there is still another 50%. Off-topic. Why 50? - SPS and LPS often cannot be compared. It's both light and flow. If you place LPS at the bottom, with insufficient blue light, the color will fade, don't doubt it. If you provide flow, you won't get coral development. Flow is not the topic here, but it also needs to be considered.

Good day, the MG lamp in the center will be lit for several hours a day to simulate noon at sea.

William

Good afternoon, so there are MH 20000k that can be installed or, for example, actinics. Or will they not be sufficient? I didn't understand anything????

Leslie

That's absolutely right. There are such MGs at 20000K. And that's why I supported the post, not only in reducing the light intensity but also reminded about the blue spectrum.

What nonsense!!! Way-x, I would go for 3x250W 12000K from Reeflux. Don't even look at the Chinese. I ordered some lamps from Fishstreet for the experiment - total garbage, they give off a yellow light. For T5, I recommend ATI: 2 actinics and 2 blues. T5 for 10-12 hours a day, MH for 6 hours. That will be good for both SPS and LPS.

In our city, Maximus set up 20,000K, and even his drones started to divide. Get in touch, have a chat. I set it up with an overly blue-purple light, but it's up to each person.

Sydney

With an aquarium height of 60 cm, the water column height will be 45-50 cm. 250W MH is excessive. 150W is needed. Regarding the topic: 2x Reeflux 12000K. White-blue spectrum. Supplementing with T5 red, blue, and actinic. It is sufficient for SPS, LPS, and mushrooms. Later, I will remove the red T5 from the set. At the initial stage, I tried MH BLV 14000K - it has a yellow tint, 20000K - the light is too blue and dim.

Brianna

The spectrum of sunlight ranges from 4500-5000K. Here is a photo taken with a simple point-and-shoot camera at 14000K in my aquarium, taken without a flash. Where do these lamps appear yellow?

Aaron580

If I wrote that the MH BLV 14000K has a yellow tint, it means I saw it with my own eyes. MH from other manufacturers with 14kK may shine differently.

Meghan

I was getting MG from Oleg (Shack) for 240. Can it really get any worse? Xenon 7000K has a purple spectrum. Could they have had 150W incandescent bulbs?

Sheila

Max, interesting information about lux, lumens, and kelvins: Sorry for only addressing Max and Yoda, 5% will be interesting to read about yellow, white, and blue.

Joseph6461

I disagree, I have a Silvania Coralstar and it has a strong pink tint, it doesn't yellow but looks pink even visually. As for other lamps, they can yellow at 10k. Regarding BLV14 - it really does yellow, I've seen it.

I don't understand why I'm starting to get confused. I have always been against lights with a color temperature of 20000K. It's too much. All corals are the same color—blue. I'm not talking about the Chinese ones; they might be labeled as 20K, but in reality, they are 14K. I installed a REEFLUX 20K, and my yellow zebrasoma turned blue.

Vincent

What I'm talking about is that the lamp can be 10000K, and the spectrum can be adjusted in any direction. I have a fixture with 4 lamps (the lamps are new): 1. SunSun yellow (10000K) 2. AquaMedic slightly yellow (10000K) 3. ATI almost white (12000K) 4. FAUNA mega white (15000K)

Rachael

fauna aqua science special? Isn't it 15000k?

Daniel

I made some adjustments.

Offtopic This is my fellow countryman who bought rock from iReef, he wrote in his thread that he found the following on their rocks: By the way, regarding live rocks from iReef. These were the first live rocks I saw. But I must say that I liked them. I found a feather duster worm (Bispira), a snail that is now crawling everywhere, 2 polyps of Tubastraea, about 7 polyps of Goniopora, a lot of Cornularia, some kind of slug, a long brown worm with a bunch of legs. That's all I could see. His thread is here:

Everyone's lights are yellowing from 10,000K to 14,000K, but why have such light in a marine aquarium or why haven't the lamps been changed for five years? Does anyone else have a marine aquarium with a yellowish tint from MH and T5 lamps? Please share what’s great about it; maybe I will also replace my lamps with yellow ones, but despite my desire, it will be difficult—it's simply impossible to find lamps for marine aquariums with 4,000K, and even then, it will be cold white, not yellow at all.

Stacey4437

What I like: From 10 to 14 tK, there are many good MH lamps. The issue is not a complaint about the yellow feeling, but rather a reluctance to: 1) clutter with additional lighting - pink, blue, and other spectrum lamps. 2) to be more precise - the unwillingness to install additional fixtures and hide the wires. However, under this light, a home reef resembles a natural one. Corals grow well under this light.

I am cleaning and closing the topic. The administration will respond to all complaints regarding who should receive a permanent ban.
