Algae from sunlight

So I had my tank in an area where there's a lot of sunlight... Not shining directly into the window, because it's facing the same way the sun shines. Could this be a problem for algae? The problem is theres no where else where I can put the tank lol

I have a planted 10g quarantine in a south-facing window that gets quite a bit of extra light from sunlight. To compensate, my artificial lighting is reduced on this particular tank.

Some even encourage supplementing artificial light with natural sunlight. It's not bad per se. Like all things planted tank, it depends. It could potentially be a problem if it puts your total light levels into algea growing range. Whether it does for your particular set-up depends on a plethora of other factors, so adjust accordingly.

Well, honestly I try not to run my marineland double bright led all that much since it is in the sunlight. the only times I really run it are later on during the day/at night.

I use one of those fixtures too and like it. If you start developing algea issues, consider total length of photo-period on the tank, both from natural and artificial light.

Could the light be more subdued from the sun if possibly maybe placing something in back of the aquarium? or say a solid black background or something of those sorts?

YES! I got a suggestion to go to a framing store and buy backing, for the back of the tank (all black) and now I have blocked one of the sides too.

I just used black construction paper and taped it on. There's a big window a few feet behind the tank. The algae is still in the wings ready to go. I put non-metal sheeting material over my glass top. I''m also concerned that the windows at the other end of the room are driving the algae. Room-darkening shades should do the trick.
