Answers:

Algae needs two things in order to grow, phosphates and light. Make sure you arent feeding your fish too much, dont let any of the food stay/ get to the bottom of the tank. You should do 20% water changes ever week to keep down the ammonia and phosphates. Feed your fish a food low in phosphates like nutrafin pellets or flakes. let your tank get about 8-9 hrs of light this will help keep down the algae. If you are unable to do that invest in about 4 nice sized snails they will help.

The natural light has nothing to do with why you have brown algae. How long has the tank been set up? Brown algae is common in newer tanks and will usually go away on its own. If it has been set up for a while then it could be from high nitrates or high phosphates. Green algae is caused by too much light unlike brown algae (which are actually diatoms) can be caused by not enough light but with all the natural light that probably isn't it especially if you also have a tank light. Here is a website that goes more into detail about brown algae and how to get rid of it. http://www.thetropicaltank.co.uk/algae.h.
