Can you let me know by this picture if this is a good or bad thing?
The green grass looking thing, it's only on one spot right now about the size of a quarter.

That appears to be some type of macro algea. You will want to pull it now if you don't have any fish that will eat it. If left alone it will gradually try to take over the tank with it's growth.

looks like Chaetomorpha. spreads fairly quickly, good for refugiums, and pod populations, can be a pest in the display. could also be other types of macroalgaes like Cladophora, and Valoniopsis.
