LED and Carolina

Laura9093

I have seen aquariums illuminated with LED light, T5, and MH. I may be mistaken, but I have the impression that under LED light, caulerpa grows poorly. I am trying to stimulate the growth of caulerpa by adding magnesium and strontium. ... I haven't seen any visible results so far, while in the aquarium with T5, caulerpa grows on its own. Under LED light, it also seems (based on my observations) that the rocks are covered not with classic caulerpa, but with some dark algae ranging from brown to black, which I find less decorative. In photo 1, there are unidentified algae, and in photo 2, there is caulerpa. Please share how things are going with caulerpa for you, what light and additives you use. I wanted to add a poll, but I probably don't have the rights to do so. If possible, I kindly ask the moderator to add a survey. What has already been discussed on the topic in the thread - caulerpa suppresses zoanthids: The right light for the sea, Discussion of fluorescent lamp combinations.

The whole reason is that the aquarium is not yet mature, your Carolina is still maturing. In the first 4-5 months, mine also didn't grow, but now it's everywhere.

What kind of light do you have? Valera, I'm not just taking my own example and I want to understand if there is a reason for the LED. Or maybe it just needs a certain spectrum. I saw an aquarium that is 2 years old with LED light from Carolina, and it has nothing! I have spots on the rocks, but it doesn't bloom... in some places it disappears where it was before, but it turns out my urchin eats it. And I have one.

I have ice, DNA assembly. As you can see, no one can give you a definite answer; they can only share their observations. From my observations, I can say that Carolina is a marker of a stable and balanced aquarium. When Carolina is growing, it means everything is good. I have repeatedly noticed that in unstable aquariums, Carolina grows reluctantly. Carolina can bleach under strong lighting, at least that has been my experience. I can also add that Carolina can shed due to kalkwasser.

The influence of pre-treatment and lighting on the growth of coralline algae during the artificial cultivation of live rocks.

Under LED light, Carolina algae are growing. I think the spectrum is more important than the light source. Carolina has started to slowly appear on the pump and rocks. I also believe that the stabilization of pH at 8.3 - 8.4 has contributed to its arrival.

You have an immature aquarium, it's growing everywhere, even in the sump, also under the ice.

I'm not only interested in mine! I've seen different aquariums, not all of them have growth... it's clear that the light isn't the issue.

I used CaribSea PurpleUp in the aquarium initially with T5 lighting, and the coraline algae grew in large amounts on the rocks and walls. Then I switched to LEDs, and the coraline algae was still present, but on the side walls (the aquarium is built into the wall and is see-through), it was displaced by sponge. I don't know if this is related to the change in lighting or the "aging" of the aquarium. Later, when the tank matures, I will add it initially under the LEDs.
