We have discussed white cloudiness in the aquarium water. Let’s go on to brown cloudiness. What are the causes of brown cloudiness? Mostly it is caused by dirt or by excess food that has not been eaten and lies around the tank, often turning the sand black. Other reasons that cause brown cloudiness is that when the sand used is not properly washed or there might be too much sediment at the bottom of the aquarium which is not siphoned off. Decaying leaves of plants cause brown cloudiness too.
Other factor that might cause this situation is the lack of sufficient growing plants in the aquarium. Though brown cloudiness is unsightly, it is not particularly dangerous. Nevertheless prolong condition can encourage disease to the fish.
What about green cloudiness? Fortunately, green cloudiness is healthy! Under excess light (sunlight, daylight or artificial) microscopic life is born which is green in colour; suspended in the water. It can also settle to become green slime over the sand, rocks, plants, glass, etc. Unless excessive, the fish will thrive on the green algae!
However, green is not pleasant to view and should not be permitted in a show tank. The cure is simple! Cut down the amount of light received by the aquarium. Of course, if the light is reduced too much, the plants will not grow.
How to clear the green algae? It can be cleared in two to four days by adding one grain by weight of potassium permanganate to every eight gallons of water. Then, change one-third of the water by siphoning off from the bottom.
On the other hand, should the green water turn yellow, the water must be changed immediately. This is due to the sudden death of the microscopic green algae causing them to decompose and turn the water yellow which means that the water is now foul and must urgently be changed.
