this tank is a year old with 2x250 MH and 4x96 actinics
if the lights are a year old its time to change them imo.
also I would strongly suggest getting a phos test.
do a water change, get some phosguard, keep feeding to a minimum. be more aggresive with skimming. if its just on the one rock take it out and scrub the algae off and rinse very well with ro water to get any algae spores off
