Thank you Peter, – it does sound logic really.
I think also the fact that I took out the filtration has an influence here. The combination of things probably.
So I have taken out some of the leaves, and for the moment added airbubbles. I will prepare the old filter again and add it.
But it has somehow rocked my idea that paroes do not use their labyrint at all for these purposes, – of course they do when needed to.
The leaves by the way were not fresh, – and they were boiled, – but perhaps too little, I think that may be the case.
