Hi! I have a five-gallon Fluval Chi with a Betta and two cory catfish. It's beet set up for about three weeks now. It has three live plants (not sure what they are, as they came in a packet of bulbs). I don't know the ammonia, nitrate, and nitrite levels. How do you figure that out? Yesterday I did a 25% water change, and the water is still cloudy. I'm also seeing a lot of brown algae. Not sure what to do about that. The filter is running nicely and the fish are active. Any ideas on why the water is cloudy? I read somewhere that brown algae is normal for a new tank, but I still don't like it! Thanks in advance for any replies!
