Due to bad planning on my part, I have set up my 180 gallon tank near a set of glass french doors in the basement of my house. I live in the Pacific Northwest so my 1/3 acre yard has many, many tall fir trees in it, so there is really no direct sunlight that hits the tank. However I have noticed over the last few months that due to the exposure of natural light on the tank, I have been getting way more algae than I ever remember dealing with in the past. It is even beginning to turn much of the substraight rocks and pebbles green in areas. Can this be dangerous to the fish at all? My natural way of thinking is "how could it be a problem?" after all, fish live in waters over-come with algae. But I am wondering if in a fish tank environment, is this something I should worry about. Thanks.

Nothing to worry about. Sounds like you have a cyanobacteria problem (commonly known as slime algae). Easiest way to get rid of it is an algae eater of some kind. Simple to be rid of.
The only time algae is bad is when it blooms and then dies. This will cause a sharp increase in DO but then it will crash and sufficating the fish. Luckily we don't have to deal with that in tanks. Also red "algae" is also bad, but we usually don't have red tides in fish tanks.
