Well it will get out of control fast if u have corals it will smother them ,also it means u have high phosphate and or nitrate both in high ppm can be detrimental to corals...
how old is your system? if its new then that is normal.
advice would be:
#1clean the rock (wipe that algae off)
2 use only RO/DI or at least RO water.
3 get a clean-up crew (turbo snails)
4 don't over feed
get a sump or refugium if you don't have one and buy some chaetomorpha.
4 limit the lighting.
Its a sign of high phospahets and nitrates it will get out of contorl. Do more frequent water chanegs, don't over feed, clean it off rocks, start running HC GFO in a reactor to lower phosphates
