How does this help with cyano? I'm currently dealing with some myself.
I'm not sure of the actual details, but in FW tanks, cyano is kept away or at bay with optimal O2 levels.
Anyone, please correct me if I'm wrong.
Also, to stick to the topic, I've seen a friend of mine keep an air pump with diffuser incorporated into their monitoring system just incase of a power outage. I have to ask how he set it up though. I'm sure there are other equipment to use instead of an air pump like the ones mentioned above.
