please explain, I didn't understand ....

Joshua9847

Set the timer for 7 hours of light, then 1.5 hours off, and then another 7 hours of light.

Alejandro

Please decipher. And who is this?

Hannah

Apparently, this referred to Caulerpa.

I would light up at night to support the pH in a large aquarium.

Anne4851

For caulerpa, there is no such thing as too little light - as the saying goes, "you can't spoil porridge with butter." In principle, it's better to light at night if you want to maintain pH; however, with a skimmer running 24/7, this argument for nighttime operation seems questionable to me. From the perspective of temperature control, it's definitely better to turn it on at night when the MH lights are off. You can safely light the LPS for 12-14 hours, but with caulerpa, you need to thin it out as it grows to prevent it from decaying in the sump.

Mario

Isn't that a lot of light in the main aquarium if I also have metal halide lighting? And I can't understand the secret of turning off the light for 1.5 hours?

Jeffrey6189

There will be no brown film of algae.

Kevin262

I really wanted to see in more detail what the dark phase is and who the higher algae are. I already understood that Caulerpa is a higher one, but are there any others?

James4757

photosynthesis toothpick accepted. I wanted to quickly and simply reply. I forgot that it's on the Forum. Let's consider it unsuccessful. Read as: blue-green algae do not develop.

Michele9664

I understood what the dark phase is, but what's the essence? These are not camels, they go into the sand...

Beth3383

The point is to let the caulerpa live properly through its full cycle. If we're going to let it take a "breath," then it should be allowed to "exhale." As for "unacceptable" - that's for me. I won't recommend keeping the light on 24/7, but everyone is free to take it into account or not.

Sheila1322

I had such a film (not only cyanobacteria) at the time of setting up the aquarium, as well as when the algae filter was started. At the moment, nothing similar is observed (at least no bright outbreaks).

Martin3206

If they start to appear, try changing the lighting mode like this - you will see the effect.

Michelle

What does the dark phase have to do with this?

Phillip9722

She will exhale anyway - nothing lasts forever under the moon.

Phyllis

Higher algae - Caulerpa, Halimeda, Sargassum, Bryopsis, Mesophyllum, Neomeris, Udotea, Botryocladia, Penicillus, Codium, Rhodophyta, Gracilaria, Botryocladia... Should I continue? By the way, there is a wonderful book by Savchuk "Reef Aquarium," see page 243, I recommend it. By the way, Pavel, there are answers to all your questions there, and I believe they are sufficiently well-argued.

Curtis

To avoid asking such questions, I would give a general definition. This is what I am actually striving for.

Craig7302

And you shouldn't have asked them, but rather corrected them in detail. That's what I'm actually aiming for. Or is it discomfort?

Brian6895

Writing is not a pain. I just forgot some things and I'm not sure if it's possible to distinguish a group of "higher" among algae. I wanted to provoke a conversation, but it didn't work out, so I'll have to strain my brain.

Chad4168

Macro and micro algae according to the definition of Ova-Savchuk. Higher and lower.. It's always necessary to keep the brain engaged - otherwise, stagnation, excess weight, and it's over!
