Won't it grow back when the lights come back on? I tried this treatment on a flatworm problem. It worked but only temporarily.

Reducing tank temperature to <74 F will also kill off most of it.

Great finding! I do run the tank at 77F. This might be a long term solution.

I would be afraid it could cause a hair algae bloom, or make the cyano worse.

Me too!
