I'm interested!
I have wondered if phosphates were leaching from my sand or rock. To test, I left sand, rock and nothing (control) in small containers with DI water for a week. Measured 0 phosphates with a seachem test kit. But still have cyano. Dosing nitrates seems to help green algae outcompete cyano where nitrates are always 0 (it also helps bacterial blooms!).
