There are several ways in which I can try to tackle this issue of brown algae.
Tetra EasyBalance Water Treatment (Said to reduce nitrate and phosphate, I also currently own this, so I will be trying this first.)
Microbe-Lift GSC Gravel & Substrate Cleaner for Aquariums (Said to reduce and bind nutrients including phosphates.)
Tetra Algae Control (Said to control brown algae as well as several other types of algae.)
According to my research there are also means of using live plants in hopes that the plants can out-compete the brown algae in nutrients. There are also certain fish/snails/etc which also consume brown algae.
