• Which coal is better to use?

  • Karen1649

It refers to which manufacturer among those that can be purchased in Kyiv. And the price shouldn't be excessive.

Kevin8087

I don't know about the price, but the best today is SEACHEM MATRIX CARBON. Those who disagree can take, for example, SERA, pour distilled water into a glass, add the carbon, and the next day measure the PO4, that is, phosphates, and will be "pleasantly" surprised!

Here on the forum, coconut charcoal was sold at a low price and of very good quality!

Matthew1280

Yes - very good coal.

Nicholas2252

Here, on the contrary, there are good reviews about Sera coal. As for the coconut - is this the last offer from Kharkiv? Yura, are you using it?

Vanessa

Not bad coal from Eheim, just coconut, but the price is a bit steep.

Jacob4800

What about the charcoal from Resun?

Matthew1280

I confirm these words, I use this coal.

Jennifer7159

Are you referring to Kharkiv coal? If so, which fraction is better to buy?

Brandi

He seems to have one faction - talk to him. But the coal/price is very good.

Monique1236

Got it, thanks! Is there still no caulerpa?

Kimberly4253

Could you tell me where I can buy it?

Debra

What can anyone say about RESUN charcoal?

Jason

RESUN - bad coal - it feels like this is not coal at all...

Amber6362

What do you think about JBL Carbomec ultra? And could you please tell me how much carbon to use for 100 liters?

Jeanne

Coal is added at a rate of 1-2 g/l. But remember that it needs to be changed every 1-2 months, otherwise it loses its properties.

April3499

The lifespan of coal may somehow be related to the amount of filtered water and the quantity of disinfected dirt that has passed through the filter, or is it really just a month or two and then it's gone?

Jason9952

Absolutely right! This is taken into account in the working interval of 1-2 months; dirt will not be disinfected by coal (microorganism death does not occur). Coal is a sorbent. The process of absorbing organic compounds occurs on its surface. As its resource is depleted, it needs to be replaced, as regeneration at home is not feasible (it requires being held in a vacuum at a temperature above 450 degrees for a long time to burn off all the adsorbed organic matter).

Jose

Thank you, Irina! In the Malawi tank, I change the charcoal every 2 weeks, and I read from some manufacturer that in a marine aquarium, you need to use twice as much charcoal as in a freshwater one, which is why I asked the question.

Emily3506

The norm is the same everywhere - 1-2 g/L. However, it should be changed according to the depletion of the resource: in a Malawi tank, more dissolved organic matter is released than in a planted tank. And in a marine aquarium, even more. That’s why the intervals for replacing carbon are different.

Helen

What can burn in a vacuum? There is also a decent coal from our region (from our manufacturer) called BAU - birch is also not bad.

Joseph

There is a technology for regenerating activated carbon BAU-A used for extracting organic compounds from aqueous solutions. It involves holding it in a vacuum furnace at 500 degrees for 4-5 hours to remove accumulated organics. If you are interested in the complete technology, I can publish it.

Joshua

Thank you, I know that. It's just not entirely correct to use the term "burns out."

Caleb6320

Irina, you are absolutely right, I thought the lifespan of coal was longer.

Melanie

Is correctness or essence important? Shall we hold a vote? I'm not pointing out to you that the word "количество" is spelled with one "л", "раствор" with one "с", "грамотность" with one "м", etc.

Antonio

Irina, I have a question regarding what you just said. Does coal only absorb organic matter, or does it also take in something else "to the chest"?

Antonio

I don't write from post to post that I'm a specialist in Russian orthography, well, sorry, I'm too lazy to use Word.

Tami

Activated carbon is used to purify aqueous solutions from high molecular weight organic compounds (as well as moonshine from fusel oils). As is known, our people are clever in their inventions. Perhaps it has other uses as well.

Bonnie

There are - in aquariums...

Kimberly3727

... and in gas masks and barbecues...

Ryan1989

Well, in manga, it's a perversion.

Catherine

Aha, not for its intended purpose. But in gas masks - just right! But if I'm not mistaken, it's specifically against inorganic substances, which is why the question arose. Or am I mistaken about something? I would be happy to broaden my horizons.

Katherine

Here it is. Sera recommends the same amount of its charcoal for 100 liters of fresh water or for 50 liters of saltwater. Maybe it's because there is more debris in the marine aquarium?

Cassandra1840

I am not talking about Serov coal, but about BAU-A, used in the production of galvanic coatings (and there is more of that G... than in both seawater and freshwater combined). By the way, its price at Ukrkhimexpo is 24 per kg. Choose what is cheaper.

Nicole7122

Then there is no point in making comments about the correctness of the terms. Moreover, such terms are unknown to Word - for that, one needs to browse through specialized literature (textbooks, technologies, regulatory documents).

Cheyenne2747

You didn't understand...

Ricky9405

We use BAU-4 coal, ask for it in Chemreactive stores.

Tammy2040

Can you provide the address of the Khimreaktiv or Ukrkhimexpo store?

Theresa5149

Kyiv, Petrovka St. Karabelnaya 5, Ukrkhimexport (RIAP plant), 467-51-45, 467-51-46, 467-51-48, 467-51-47

Devon107

JBL coal is good, it does not contain phosphates and nitrates, and the pH is adjusted for the sea!

Dana4701

How can coal have pH? But regarding phosphates in coal - that's true... I'm curious, how are phosphates in BAU-4??
