Hello,
I've set up a small tank month ago filled with 6 liter, some gravel, Hemianthus callitrichoides, Vesicularia dubyana, Lemna minor, Cabomba aquatica, Monosolenium tenerum and Riccia fluitans.
I didn't istall any technic except a light tube.
The tank is occupied (in the non-microscopic range, pure-eye-visibility) by: Physa marmorata, some Planorbidea and Asellus aquaticus.
Wateranalysis: pH 7,2; KH 3; GH 7; NO3/NO2 not detectable (Tetra Test-Sticks)
Waterchange: Once a week, 0,5 liter.
All plants are growing and snails and woodlouses are in good health, reproducing themselves.
But why die any other creatures than the named ones? I tried several Melanoides tuberculata, one Apple-Snail and Crystal Reds as well.
All of them are in heaven now...
But why?
Where is the mistake?
Helpless remains:
Verena
