Welcome to TFP!

It still says TN over there <----

You can spray some bleach on the spots to help kill it. Once the test kit arrives it will be time to SLAM Process to kill the algae.

If its at the water line or higher than you'll have to scrub them off using a non scratching pumice stone, especially on the grout. You can get them at pool stores, home depot, Ace hardware. I'm sure Walmart sells them. The steel bushes don't do much on the grout.

I prefer to use Ace's..
