My new tank (20 gallon high) has been getting persistant brown algae
on the plants. I've read that alternating the light schedule for a
few weeks can help cut down on the algae while still letting the
plants grow. Has anyone tried this?

Tank setup as follows:
5 danios
3 ottos
7 ghost shrimp

Flourish 1X a week
Flourish Excel daily
40lb flourite gravel

lighting - 85 watts
plants - 4 swords, 2 sagitarius, 2 mondo grass, 1 wisteria, 1 sunset
hydro, 1 hair grass, 1 banana plant, (2 fake plants (growing very
well))

Tank parameters - taken yesterday
Nitrate - 20
Nitrite - 0
pH - 6.5
