I'm in the same boat. I have a few patches of HA but my nitrates and phosphates are zeroed out. It has been suggested several times in the forums that macro algaes like HA can take up PO4 and nitrates before they get a chance to be read. HA is a resilient bugger! I have HA growing under rocks where there is NO LIGHT! Seriously, WTF?!
