This is called a diotom bloom that is typically telling you it's nearing the end of cycling. It will disappear usually in a few days to less then a week. Unless you are using tap water at which point it will continue on forever. One way to speed up the bloom ending is to turn off your lights for 2 days or so.

Thanks Steven, I feel stupid now because I just read the (read this first post) which explains all about diotoms.
All the best and good luck with the tank.
