🙂 Well, I am no expert 😉 .. but I can always share my own experience as far as it goes. I am certainly not always right in these matters.
But I agree with you that it sounds like a perfect ground and built up, – and well, sometimes it may prove a problem with too much organic material, and too many snails etc, – sometimes it doesnt give any problems.
I use extensively spagnum in all tanks, and leaves, – never any normal gravel. I made an experiment with a tank with lots and lots of oak leaves, actually wanted to make it only leaves, – but it didnt work out, – its clear now theres too much organic material in there, – so theres so many algeas now, – thread algeas… however the ornaticauda’s in there are thriving and breeding .. so … 🙂
If I cleared that tank for all plants and leaves, I am sure I would see those kind of ‘paramecium’ clouds, because its too rich on nutrients I think. And it may not be optimal, but I cant from my experience say that it is very bad either.
