Getting rid of Cloudy water in your aquarium

There are a couple of reasons. Let me go through the most frequent causes

1. Bacterial bloom. The foremost reason for cloudy tank water. This happens in almost all beginners tanks that are not cycled properly or not cycled at all. I'm not going to go into the specifics of the exact process of the water clouding . Lets just say the bacteria that causes milkiness grows very fast in uncycled tanks. In some occasions even old tanks get their water clouded up.
2. Excessive feeding, which in turn causes the water to foul up, thereby leading to bacterial bloom again.
3. Over-cleaning tanks, this leads to destruction of the good biological bacteria colonies and and subsequently cloudy water
4. Driftwood, bog-wood, substrate leaching material into the water
5. New substrate that hasn't been washed well enough

Methods to get rid of cloudy aquarium water

1. water changes all the way.
2. Overfeeding causes water to cloud up. You could try reducing the amount of food you feed the fish
3. Remove any new driftwood/bog-wood you introduced into the tank and perform a water change and check (50% water change should be fine)
4. Turbid water from the Tap (check your source of water i e well, municipal etc)
