sunlight good or bad?

See the displays with Solar-tubes, but as for putting in front of a window, heard (no experience) can cause unwanted algae growth and cause tank to go over temp.

Our tank is not infront of a window but we did notice sunlight is going into the tank, we are tryin to figure out if we should cover the window or if its goin to affect it that much, its only a corner of the tank that is getting the sunlight

My tank sits in my living room and gets direct sunlight. This would cause that panel of glass to bloom with spectacular algaes quite quickly. I had to close the blinds in my living room to prevent this. However, now I am running nutrient reducing media that works really well (NP BioPellets) so out of curiosity I opened up my blinds again. To my surprise that panel of glass does not get algae blooms anymore. So the cause was one part direct sun and one part nutrients in my tank.

I did/do not notice extra heat in my tank from the direct sun.

As long as it doesnt cause the water to overheat natural sunlight is good for your tank. There are a handful of people (in the USA mostly) who have set up coral greenhouses in order to use natural sunlight and save on the electrical costs of large scale coral growing.

I have a tank in the sun and must keep the blinds closed at all times. I have a chair tucked up close to them to block it........tank is in my bedroom and yes it is a pain, however I feed my fish a lot and have cut down but still find it is originating on the side closest to the window.
