• Pico reef with LEDs

  • Michele9664

Introducing my small reef tank. The system is 23 liters, with a net water volume of 17 liters. Filtration is handled in the side compartment via a sump with live rock and a bag of Seachem's Purigen. The rocks are live rock. Lighting is LED only. The light is powered by two timers—first, the blue diodes on the "Piranha" modules turn on, followed by the main blue/white lighting diodes. The moonlight is on 24/7. Livestock: a yellowtail damselfish (Chrysiptera parasema), a brittle star, many small brittle stars and asterina stars, fuzzy worm polychaetes, 2 peaceful hermit crabs. Lots of corals—various types of zoanthids, palythoa, protopalythoa, discosoma, briareum, clavularia, sinularia; among the LPS (large polyp stony corals)—Caulastrea, Euphyllia, Acanthastrea, and others.

When was the system launched? When were the animals planted? What LEDs are used? What is the growth and color dynamics of the corals?

I would like to clarify: The question was more in the plane - the palette was brown, and it became bright green. The discs were blue-brown, and they became purple-red.

How many diodes are there in total and what is their total power? How much did the light cost? Visually, what power can the LED or MH be compared to (if appropriate, considering the very small volume)?

The colors do not change. The animals you bought are the same color as they were.

10 1-watt LEDs + 6 "piranha" modules (they were lying around unused, so I used them, but they are not necessary). The light cost about 600. In terms of price, low-power fixtures are relatively unprofitable; higher power ones are not much more expensive, but believe me, there are practically no alternatives in terms of light quality, especially for small aquariums. Visually, it shines like a white-blue PL lamp, probably around 36 watts. Trust me, it's very bright. The LEDs have a feature where they shine directionally, while the lamp spreads light in different directions. Here, Ray demonstrated, for example, how 3 LEDs illuminate 15 liters, even from a considerable height:

What is the total power of the modules? It seems to be around half a watt? If I'm not mistaken... I'm just curious what was compared to a 36-watt lamp. Can you take a photo of the light fixture itself? I'd like to see how it's assembled. He wasn't filming in complete darkness. The "background" is quite bright. So it doesn't seem very representative. And one more question about water changes. How often and how much? Is the water freshly prepared or from the reef aquarium? Off-topic (I apologize if I wrote something incorrectly.)
