Oh, and what a lovely tank, BTW. Great work. Best of luck with this algae outbreak. I know what it's like to see a lovely tank waste away before a BBA onslaught and it's very disheartening. I am trying to get through some algae problems of my own with the BBA, and I can empathize with you that it is very frustrating. I really hope you are able to get rid of the algae before it takes out the more sensitive and the more slow-growing plants. Hair algae just hasn't been near a problem at all for me as the BBA; it is much less hardy. Take heart in that.
