Natural sunlight?

[Canadian Man]

Last year Tony and I had a chance to meet with Rob Toonen here in Calgary. We were discussing the natural light thing and the amount ones tank may receive with a south type facing window. Or a few hours of sunlight.

He said that the amount of light we would receive in a scenario like this is so minimal that it will not provide any significant benefit with regards to the critters in our tank that need light to survive.

That's the word from the expert. So unless we have a specific setup. eg.solatubes or many skylights like the fellow with the 2000G aquarium I am afraid we will get no benefit.
