Are you in Hawaii? Is there any seasonal temperature change in your location? I don't know how much temperature change yoiu can accomplish with fans, but it is worth a try. Also, do you have a canopy or hood over the tank? If so, remove it and try an open-top tank.
During our hot summers, I usually have several small patio ponds going. Even with shade, water temperature stays in the low to mid 80s. When I have tried to grow moss in these tubs, it turns stringy and brown like your photo and usually dies before the end of the summer.
