i jsut beat a small uprising of cyno.. i did a partial black and added a nano korialia for flow and in 5 days there is bareley any trace. some spots it was 2inches around and now is barely noticable. i also have move aPH to cut the surface water.

"i did a partial black and added a nano korialia for flow"

What do you mean by "partial blac" and what is this nano korialia that you add?

Black out. i only had my lights on for 3 ,1 hour periods. the nano korialia is a powerhead used to add more flow to front of my rock face. this over a 5 day period has obliterated almos all signs on cyno.
