I thought brown algae tends to flourish in newer tanks and then slowly fades away as the tank ages, no? So far, I haven't had too much trouble keeping my loach content in my month-old tank. I am concerned that my tank won't be able to support brown algae long term.
Note that this tank has many plants (and some other algae) competing for nutrients. Is there any one nutrient that causes brown algae to grow over other types of algae?
