NOTE: THIS IS A BRACKISH SETUP, but i am looking for any ideas...

what is the appearance of good and bad algea?

i have a cycled 29 brackish that about 1 month ago i added live aggrogite to. i have since lost a couple of fish (weakend and fell to the power of intakes), now my gsp is black, not eatting and lying down (not his usual behaviour by far). tonight i did a 1/3 water change which did help his color for about an hour.... now he is back to black... i have even tried tempting him with ghost shrimp, those are hiding from the figure 8 by sitting on the gsp's head...

upon a thourough inspection i found my first colony of algea since adding the new media, a small light green/brown on glass (looks like a normal algea)... then found a kind of light brown kinda clear silky fur algea growing on an ornament and only in on piece of this multi piece ornament... on this piece there are 4 small patches totaling no more than one inch in size combimed...

anyone out there know thier algeas? please help!!!! i cannot afford to loose any more puffers!
 
There is no such thing as "bad" algae, but it is often a sign of excess of nutrients (mostly nitrate and phosphate) which fuels the growth, which is why its important to also post water peramenters, as the algae isnt whats is doing it, but a byproduct of what is.
