I need advice!!! Aquarium 200x65x65. What power should the metal halide lamps have if the lamps are 15 cm above the water surface? What Kelvin rating is better to choose? Maybe mixed. And maybe someone else has some suggestions.

Sarah7284

Phew... And what about the reflectors? In general, the reflector and the lamp determine which surface can be illuminated... In your case, a reference point can be considered 3mg per 250 (this is for hard corals). But this is somewhat like the "average temperature of patients in a clinic." The fact is that the color temperature has a significant impact; for example, PAR 250 at 10k is close to 400 at 20k (see the figure). The Reef Lux lamps are considered relatively universal (color/growth)... again, the question is whether you will use T5? If you plan to keep soft corals in the aquarium, the light requirements are significantly lower.

Reflectors like in the picture, I'm switching to hard ones now, but there are also various disco anemones, zoanthids, etc. Suggest an option. Since I installed 400W 20000K, it's too much. The colors are overwhelming.

Monique1236

I can't see the pictures. As for "it strains the eyes," it is critically important what ballast is used with the lamp.

Bethany

I see. I don't know this reflector, but considering its elongated shape, I would lean towards 2 by 400... But why was the choice made specifically for this reflector?

Frederick

While I'm waiting for the electronic ones, I took the electromagnetic ones for a test. I still need to decide on the lighting, and then order the ballasts since the price of this equipment is not that of a children's toy.

Jeffery7866

What kind of lamps did you install? Shouldn't 20000K be harsh on the eyes?

Natasha7622

two and set, a bit too little. Either the middle or the sides are not illuminated.

Danny

CoralVue 2 pcs.

Sheila

Is there a lot of blue in the electromagnetic spectrum? What kind of lamp is that?

Julie3950

A lot of blue and white, before it was 10000K, I liked it more (I don't know how the corals feel about it).

Stacy6866

"Does 'eats the eyes' mean that it shines in the eyes or that you don't like the color?"

Carrie1606

No, it's just that even the fish seem to have started blinking.

John

CHANGE THE REFLECTOR

Brent7831

Hmm, strange... quite good lamps..., are you sure it's CoralVue? There are cases where they sell something other than what should be in the box... (there are such characters) For a 2-meter long aquarium, you need 3 MG!!!

Paul

It seems that CoralVue is written on the bulb. I'll take a closer look in the evening.

Jesse3979

t5 will definitely be there, like dawn and dusk.

Alyssa6727

15 cm is a bit small for MG... there will be fish soup in the evening.

Angela6489

there is no possibility to raise it higher

Jason9952

What is the actual height of the water column? At what depth will they be rigid? What am I getting at... ah! Maybe at T5, considering the need to place it close to the water?

Richard2180

I will think about how to raise it by at least 5 cm, will that save me?

Andrea

Why did you choose such reflectors? The aquarium is narrow and long. I need to illuminate it lengthwise, not the floors next to the aquarium. Of course, if they are raised by another 15 centimeters, then it will illuminate the entire aquarium.

Kimberly4253

Umm... let me try to help you this way. Here is the article. Here is the translator. Read it, maybe by analogy with the tested reflectors, you will weigh all the drawbacks and make a decision that suits you.

Larry9400

And yet, the distance from the water's surface is the answer to the question of why these two reflectors do not cover my aquarium. This is the first question. And still, let's return to power and Kelvin.

Laura7633

3 at 250 watts and Lumenbrite, Lumenmax, Lumenarc (underline the necessary) would brilliantly illuminate the entire aquarium.

Kellie

1) Because they are lightweight and the reflector area is small. 2) What interests you about power and Kelvin?

Heather

which to choose 250 or 400 and how many Kelvin

John3142

Oh... hmmm... look, HM 10K is probably one of the most popular "white" lamps... also check out BLV (Ushio) 10K... you should like it... it's 250... I think with such a color temperature 400 you don't need it...

Aaron

I installed a 250W 12K, and it became much better.
