Cloudy tank

Cloudy how? Milky cloudy? Green cloudy? What are the water parameters -- ammonia, nitrites, nitrates, pH? Is it planted? What are its inhabitants? The more information we have, the better people can help.

welcome to the boards... you will definitely get help in one of the other rooms... maybe General Freshwater.

details are the key. i'm gonna suggest it's a biological filtration thing. what kind of biological filtration you using? or possibly over feeding can make water cloudy too. but water parameters can be great in figuring out a problem..

Have you added anything that may release tannins? I had a greenish yellow color for quite awhile after I added drift wood. Do you check phosphate levels? this could cause an algae bloom in a freshwater tank.

I think it's algae as when I take some water out, it's pretty green. It's not in a heavily lighted area (ie, not exposed to sunlight) - I have two algae eaters, three guppies, a couple of tetras and an angel fish. Any ideas?

How long are your tank lights on per day?

Do you have any live plants?


I also noticed that you are very overstocked, I would re-home the angel fish and if the algae eaters are chinese/golden algae eaters then I would re-home them too. The angelfish needs a larger tank and the algae eaters (if they are chinese/golden algae eaters) will grow really big and when they get mature they tend to stop eating algae and instead suck the slime coat off of their tank mates which often kills the fish that gets it's slime coat sucked off.

Once you re-home the fish I mentioned I would increase4 the number of tetras to six as they do best in schools.

Back on topic, overstocking may be contributing to the algae as more fish tends to mean more waste which means more nutrients for the algae.

Hope this helps.
