Here is the problem:
last Sunday, I did my weekly water change (50%), cleaned and fertilized. the next day, my wife told me that the tank is cloudy. i inspected the tank once i got home and sure thing I found that I did not plug in the filter in the electricity socket. I plugged it thanking that the water will clear in a day or two. it has been almost week since than. I changed about 80% of the water on Thursday....and guess what it started as somewhat clear but by the night it got to be very cloudy. the water is not green and it does not smell or anything. it is just cloudy.
Can you please help
by the way, the tank has been set up now for about 4 months.
