My foggy tank

Question
We have a fresh water tank in my class room and the water was really foggy so we fixed the ph and it got a little better but i still dont know what to do....

Answer
Hello Becky,

The best thing to do would make sure no one puts chemicals in it (as this can kill bacteria, algae) and make your water cloudy. Also if you do a big water change over 50% then your tank well have to cycle again and it well be cloudy for about 1 week strait.
