Unfortunately, city water. No well.

I’m reentering the hobby after a 30 year absence. Have tank and equipment and about ready to go. (I’ve been watching Aquarium CO-OPs YouTube channel for a couple months.) But testing my tap water I find it “off the chart” for phosphates. I’ve read anything 2 and above is going to result in algae problems. I’m 10 ppm. Any advice? I plan to do a heavily planted tank. Am I going to need a RO setup? If so, can you point me to a how-to video or article? Thanks. [BTW. This is my first post.]
