okay i just got home and i have brown algae all over my sand?what is this:pooh:
I'm no expert. But I have some experience with cyano and diatoms.
I would run a decent amount of carbon filtration. Carbon absorbs dissolved organics which smell and can cause cloudiness.
Water quality needs to be scrutinized. If you have Cyano, red slimy spots that release bubbles, and it's on a rock that can be removed without jacking everything up, I would pull it out and scrub it with a toothbrush under RO water or old tank water.
did you add anything recently? if its a really bad smell, it should be from bacteria and that should mean something is rotting in your aquarium. maybe not from fish, but it could be from other organisms that died.
