Black stuff growing on rocks

I guess all you need to do is slap a designer name on it and start the fraggin.

ok, i have a bit of a cyano breakout, black to purple black in colour, i am only running aqua clears, and 2 fans (waiting on some money for a canister). ive derived that i left the lights on too much and my newly added rock leached some phosphates, and then bam, black covered everything. all i have is the LR and some sand in there, and ive been cycling for a few weeks now. so what tips can i get to get rid of it besides turn out the lights, change the water and scrape it out of there. also note STRICT BUDGET. for now

So noone knows for sure? It does look neat, just hope it's good.
