I have a new 55 gallon tank set up it's been up for a little over a week and has been perfectly clear until yesterday when I added a heater and some live plant bulbs to it.When I woke up this morning it was cloudy? I put new carbon filters in,some ph balance tablets and water clear but nothing it's still cloudy. There are no fish yet i'm still trying to decide on what kind of tank I want to have
