My aquarium is cloudy! PLEASE HELP!!!?

Question:

Hi! I just bought an aquarium from petco 2 days ago and its one of those with a built in undergravel filter and air pump. I set it up by following the directions...and turned it on and it looks like its working because it bubbles up....but now 3 days later the water is all cloudy :(. Is this normal with an undergravel filter? or do you guys think its a malfunction? i havent ever had an undergravel filter before so i dont know how well they work so it might be normal but i wanted to check. Thanks so much!! :)

Answers:

If the water is cloudy green, you have a serious light related issue to get an algal bloom that bad that quickly. Make sure it's only getting 8-12 hours of light a day between your tank light and ambient light. If needs be, move the tank and install a timer on your light's powercord.

Undergravel filters work very well once you have bacteria in the tank. However, when you're first starting a tank, you can get pretty high ammonia levels. Try putting some activated carbon in front of the output. It won't get rid of ammonia, but it will probably help clear up your water.

Did u use new gravel or the u had from previous aquarium ? The watter is not ready yeat its working and the claudiness will disapear i may take 7 days untill the water is ready so u can add fish inside .. so 99.99% ur filter is fine it can be from ur cravel can be the proces of water .... dont rush to replace it u have 14 days i think to return it just read ur recite... good luck

Tank cycling is very basic and had you researched you would have known that biologically dead water needs to build up bacteria.

I think that that's just normal and it should clear up soon.change the filter or take it back and tell them wat happened they should give u a new one
