seeds and bug issues

I have seeds starting in flats. Most of them do pretty good. Some of my soil flats however get these little gnat looking flies. I also have some green algae looking stuff on the top of the soil. Not like a mat, but some of the perlite is a little green.
what am i doing wrong or what do i need to do?

The insects are fungus gnats. They are eating fungus that is growing in your soil. The fungus is growing in the pots due to overwatering and cool temps.
I would recommend that you lighten up on the watering and add a little air flow. A fan on low would be good if possible. You can use some diamatious earth to rid your pots of the gnats or you can purchase some safers soap and start spraying on a regular basis. Good luck......
