Sometimes the solutions aren't as easy as nuking a tank turning off the lights putting algae eaters in sometimes you have to base it off the fish that you have one of my wife's tanks has Oscar said Terra plants and other fish so we can't put guppy grass in it or Bristol noses that are small. So we put a dozen of snails in there and they seem to help clean the tank. What were the other tanks they have bristle noses snails and guppy grass what will guppy grass do you might ask they eat the same stuff that algae does so it takes away food from your algae it also creates a shade in the tank which the algae eats. This is a little insight from Shirley's aquarium coffee shop startup.
Do not nuke tank, it'll just come back. Untill the imbalance is fixed or something is put into tank that can predate it you'll just get more
I personally would not nuke the tank. Any algae is an imbalance of light and fertilizer. Balance them out and BBA will go away on it own. That said, I should not be in canister filter. Aslo, Id get fish or shrimp to eat the algae. Good luck.
