Light is said to be from 1W/l at 10000K, and as far as I know, powerful lighting is needed specifically for actinics. Among MH lamps, there are Silvania AquaArc 10000K and some others at 13000K, but I don't think there are any others.
You should probably decide what type of aquarium you want. If you just want to know what kind of aquarium you can afford, then on the forum, if you read the posts carefully, there are answers to all your questions.
How pretentious...
What is wrong with the experiences of other people?

Hello, for your 200 liters of water, a 150-watt metal halide lamp plus 2 actinic lights with a blue spectrum will be sufficient. I have 550 liters with 2x150 watts of metal halide and 2x40 watts of actinic, in a mixed aquarium with hard corals, and everything is doing great.

Indeed... This photograph can say a lot... There is much to think about...
An interesting feature: the photo can be divided into three sections. The first section is where the light from the MG falls. This section is "clean." The second section is where the light from the LL falls. Here we observe some "brownish-red" algae. The third section (in the middle) is likely the area where light from both the MG and the LL falls. There is a clear predominance of "brown" algae.
Is this a random coincidence? Or is it true that all my observations are correct...

Hello, these algae are impressive, and light plays a secondary role here; most likely, the phosphates and nitrates are out of order.
Omar3497
In the photo, there is one aquarium, but it is illuminated differently in various areas... So the concentration of phosphates and nitrates is the same everywhere.

I looked at that topic, and there are some photos there. In general, the white spot under the MG in this photograph is due to the camera's insufficient photographic latitude. A brighter area simply turned white and wasn't captured properly. If you look closely, you can see the same brown coating in the shadows on the rocks. I'm not an expert on the sea, so draw your own conclusions.

Absolutely right. We set it up and don't overthink it. Well, if you want to create a hassle for yourself, you can practice with LED lights, but that's for enthusiasts. For example, to keep hard corals (and most anemones) under LED lights, it's highly desirable to have 2 watts per liter, and definitely not less than one if you're limiting yourself. Let's imagine a 300-liter aquarium, so you would need between 10 to 20 LED lamps. How to fit them under the lid? Plus, branded lamps are not cheap, so it doesn't make much sense. But theoretically, it's possible, so if you have few problems in life, go for it.

Then why did Platax recently install MG?
Russell8484
Naturally, MH is better! But if it's not possible, you can temporarily (for 8 years) manage with fluorescent lights. By the way, you can congratulate me - I set up a 500-liter marine aquarium!

Fluorescent lights: 4 T5 and 2 actinics, each 1.5 meters long.

not everything - what and how was contained in Rey (Platax) - ask the author himself - but take my word for it - not all 8 years were like this.

Wow! That's very grown-up. A gift for February 23rd?
Congratulations!
P.S. What kind of sand is that, is it aragonite? Where did you get it?
Rodney
The comrade took aragonite from Shumov in Moscow, while I have river sand mixed with ground shell.
Jeffery
Ah, I remembered about the shell. Damn, I understand that in the vastness of the CIS, aragonite sand can only be bought from Shumov.

It's strange, the page of the forum doesn't open.
Joseph9057
Ray, thank you for paying so much attention to this topic. We can close the topic with a quote; I will sign it myself.

- but in principle, it is possible to manage with fluorescent lamps.
Amanda
well, here we go again
they wrote that it can be done without it - but it's just not the same - however, you "get used" to your aquarium - put a couple of animals in it - and then you might change your mind
of course, M.G. costs money, just like everything related to the sea, and in which cases you can do without M.G. read above
