Suggestions on my new scape 100g rimless

[dannsafly]

Thanks for trying to help.

I changed 60-80% of water twice during first two weeks. Sunday is when i do my last water change. On Monday when I come home from work I discovered that S. repens lost most leafs and Fungus started growing like crazy.
Problem is that if fungus cover my HC it means that HC is or will be dead. When I carefully tried to remove fungus I then discovered that my HC under is dead. Not even one green leaf

Pearling like crazy means that everything was in balance. Is that correct? What kind of care should I give then?
Starougyne is still dead and fungus started to grow on AS There are no plants in my tank at this time. Everything is dead or half dead or covered with fungus.
There is no point in trying to make it work when there is no plants left, only roots and most of them brown/dead. Only one lonely Blaxia survived


Funny thing is that my 29 biocube gets less attention from me. Tank looks great. Starougyne looks healthy, green, no sign of any algae

I will upload pics tomorrow.

Thanks,
Marek
