I have recently started getting some weird black algae on my sandbed. I have never seen it before. I have been fighting HA for a couple months now and it's went away and it came back back about a month ago. I recently installed a BRS reactor and running GFO and GAC in the reactor. My levels are fine but even though phos. shows 0 I'm sure there is some there due to the algae infestation. the problem that I have is now there is some black algae accumulating on the sand. what is it? i hope its just die off from the gha but maybe somebody can help identify it. ill post a pic shortly.
