using natural sunlight?

[nanmer]

I have my first planted tank, a 2 1/2 gallon shrimp nursery, small but has inspried me to greater things. I am considering planting my 50 gallon now. My house has awesome windows, I am a plant enthusist and choose my house for its lighting. I read so much about artificial light requirements, can this be done with natural lighting? Why does every fish person always say "keep tanks away from the sunlight"? Why would one pay for artificial lighting when it is as close as the window? I know the sun will warm the tank, but I am considering doing the whole "great stuff" foam thing on the back, so the only exposed area would be a marginal or bog area planted area near the top and diffused lighting from the sides. The tank would only receive full light from about 8 am to 1pm.

Is this a consideration or do I have to opt for artificial light?

Thanks in advance!

it can be done and is done. 'natural tanks'

you may need to find nutrient hogs (usually some form of floating plants) green water usually becomes an issue. a few of my tanks get sun with o real issues except in winter where I have to supplement the light or watch plants die back.

it can be done just a lot harder to be stable. i would make sure to have co2 also.

Thanks for your answers and suggestions. Let the planning begin!

or use low light plants and emerged/floating plants (like duckweed, which you will have to scoop out every day or so) that can use atmospheric CO2 and out compete algae for nutrients in the water column.
