Hi everyone! I live in Orlando and just bought my first home, which came with a pool! It was a nasty swampy green before, but I've been doing a crash course this week and the rehab is going well.
I have a company coming Friday just for good measure. I am noticing these white spots on the bottom. I assume this means that the bottom of the pool is stained with algae. Does this mean I need to drain the pool & chemical clean? Or will some hard brushing, shock, and a vacuum be enough?
