My tank doing fairly well overlooking algie here and there amonia 0.25 at times . Had arm in tank moving a clam after I had my arm out for a few minutes it smells like fishy salt water harbor not rotton but like the harbor. Tank doesn't smell room it's in either . Just my arm and I smell this every time I put my arm in it. Good or bad? Ya I know the threads on bad for the arm . Spent my life in some of the worst liquids in the world including radioactive water. I'm still alive cancer free as of 9:38 pm today. LOL
