I have a blue green sediment showing up in our water line. It's so prevalent it clogs our aerators every 3 or 4 weeks. It has clogged the diverter cartridges in our showers so that we don't get any hot water. Everyone seems puzzled as to what it is. Photos attached

How old is the heater? Do you have a recirculation line?

Heater is ~5 years old. It has a recirculation line

I also tested my water yesterday with a home kit. Nothing was out of the ordinary except my PH was very low. between 3 and 6. It's NYC so the tap water is usually 7.2. The lead, iron, copper etc were all normal.

That is likely just mineral sediment. It can be drawn backwards off the bottom of the tank through the recirc line at times of high usage and then it winds up in your aerators. There should be a check valve on the line to prevent that, but usually, if there is one, it's a swing check and they jam open more easily. We like to see spring check valves.
