So take a look at this picture.. This rock has two black spots like that... Feels like a leather chunk when i touched it with a metal tool...it is verry "slippery"
anybody has an idea about what it is ?
Also my live tock is constantly bubbling.. Also my cheota bush.... Nitrate final decomposition to gas out of my tank? I hope
Heres a pic...
My rocks lately started to fill up with huge purple and red algee spots... And i have tiny creatures crawling in every corner even on the glass...
