New tank been up for 4 months now. Parameters are in line but having this growing rapidly over the bed and rocks. Is this cyano? And if so what causes it?

Nice Monitors in that app there. where did you get that and how much all that set you back if you don't mind me asking? As for answering your question looks green to me and cyanno is red slime if I recall correctly. But I do believe it can manifest in other colors too

It’s a free app called aquatic log. I physically test all my parameters every other day and log it on here.
