The algae started showing up when my tank was fallow.  I would feed the shrimp bits of silverside as well as the corals.  Fish have gone back in over the last 6+ weeks and are fed once per day, only as much as they will eat.  I have a tunze 9012 skimmer, hob fuge with cheato, canister filter that is cleaned thoroughly monthly.  For power heads I have an mp10, mp40 and a koralia 750, tank is 55 gl with 65 lbs lr.  Lots of snails including sand sifters, and hermits.  My last tests showed my alk was low (6).  I don't have any other algae issues, I think the branching stuff came in in a coral frag.  Any other suggestions, Im not sure if it's over feeding as I'm careful.  What else should I be looking for?
