Cycling New Tank

I did everything that was said. I am currently running two filters and I have about 10 plants and my driftwood in the tank. At first my tank was cloudy due to the eco, then it cleared last night. When I woke up this morning, it was cloudy or murky again (not sure if from eco). What causes this and is it normal?
 
probably a bacterial bloom its normal and will clear up soon
 
A bacterial bloom is white. I have had one and I did a 50% water change. It went away as quickly as it appeared. I don't know why I did a water change it just seemed like the right thing to do.
