I have been running my water farm for a long time.
Winter is known and there are no other places from which samples can be taken.
And this tank of mine with water and decaying plants was supposed to be a way to survive the bad time.
However, I was a bit disappointed with the results.
I was taking too few microorganisms and still the same.
However, recently something has changed and you can see it in the video.
I didn't focus on any Protista, I just wanted to boast about their amount.
