Alge on the lawn

[LawnPro in NC]

I recently renovated my lawn. I sprayed it w/round-up twicw and scraped it with a york rake behind the tractor. I core areated it and applied lime at 30 lbs per K. I seeded it and the grass started to germinate. Watering once per day 15-30 min. A week later I have alge growing and not all the seed is germinating or seedlings growing. I have not watered for 4 days now and it is still damp.

I raked some with a steel rake and ith alge is just on the surface.

I was thinking of running a power dethatcher over it and reseeding.

Just glad it was my lawn.

Any suggestions, should i just leaveit alone or ?.

With the high 80's we've had I think our seeding window maybe open longer but I need to do something pretty quick.

Thanks
