Off-topic. In a year, only 21 people said thank you... what the... is going on on the forum? Is everyone in big business or can't they read?

What do you think about the depth of the soil? Is it worth making it 10-20 cm? I have 2-4! What are the consequences of that?

Nothing. Just build the filtration system on different principles - a powerful foam generator, refugium, a large amount of live rock, good absorbers.

Oh, thank you! I basically suspected that we are compensating for all of this with new technologies (like traffic police compensating for the lack of horses with flashing lights). Pennik, stones, samp, denitrates, coal, etc. all of this is available.

I have another question! I have 1-2mm sand in my aquarium, and in the algae scrubber, there is 0.1-1mm sand. Should I add finer sand to the aquarium for a larger population of living organisms in it?

I will try to format the collection as an FB2 e-book - it's so convenient to read on a reader. Is anyone against it? Can we post the version here?

It would be interesting. There are also other, more precise books in Russian: "Wastewater Treatment," Lapitskaya; "Aerobic Stabilization of Sludge," Abramov, 1976; "Wastewater Treatment in Industry," Proskuryakov. For people who are more interested in the topic than just figuring it out with vague words, it is very useful to read.
