Hi @_Maq_ & Everyone,Algae spores are ever present and you cannot sterilize your tank.
Even though it’s non chemical, UV triggers formation of ozone that kills ick, fungus and algae spores, so its effect is equivalent peroxide. I spray peroxide on exposed plants and surfaces when I drain down the tank in WC.Hi @_Maq_ & Everyone,
Use of a UV-C sterilizer will kill water-borne algae and fungal spores. This approach requires that the so-called 'dwell time' and UV-C dosage is optimized. No chemicals required.

I'm trying to employ common sense; if I'm wrong, please, correct me:UV triggers formation of ozone that kills ick, fungus and algae spores
Hi @_Maq_I wonder how can UV-C lamp kill only algae and harmful fungi and not to kill "good" microbes, par example nitrifying ones.
Hi @MitchelI can't control the algae anymore so I've decided to break down the scape and start all over.
I've read that majority of nitrification occurs in the sediment, but also in the water column. When reading papers on this topic, light does not seem to be of scientists' concern. So, I take it that these microbes are only moderately inhibited by light.My understanding is that nitrifying bacteria preferentially multiply in the absence of light. For that reason, the classic canister filter is an ideal environment in which they can flourish.
@Mitchel what have you tried to get algae under control? The usual best first step is to reduce lighting for both intensity and duration.
The tank was in great shape and healty. But I had a long time hospitalization. When I got home, everything was covered in algae. And I just don't want to spend a lot of time cleaning up the mess.Hi @Mitchel
With which species of algae and/or cyanobacteria have you had problems? Perhaps you could attach some photos?

...it is clear that since then the scientist can identify bacteria/archaea with much better certainty.
Hi @_Maq_The paper is truly ancient.
