In the past few weeks, I removed previous grass/weeds and rototilled a small area to replant with fescue blend grass seed. 10 days after with many of the seeds sprouted we had a heat wave (100+ temps) and suddenly I had green algae growing on a big portion of the new lawn. It is choking out the small grass starts and spreading. I have tried a 1:3 ratio of H2O2 to water as recommended by some but it didn't help. Any suggestions on killing the algae without killing the surviving grass starts in the area?

Try to use 1L Ready to Spray Moss and Algae Cleaner if it's a bigger lawn you can use Tidal Backpack Sprayer just mix the 1L Ready to Spray Moss and Algae Cleaner and you're good to go. :)
