We have been batteling what we think is hair algae for months in our mixed reef (see video below). Currently 9 days into using Reef Flux. Every couple days we brush away as much as possible but continues to come back. It's not possible to remove all rocks. Also, now its spreading to sand bed. When patches are removed, they are not green but brown/purple. Needing identification if this is GHA, if so, other possible remedies. Thanks,
