You don't have enough CO2 in your water. A ph of 6.8 and a kh of 5 is about 23ppm CO2. Reduce lighting, increase CO2, x2 dose Flourish Excel for 10 days and trim out as much of the algae as possible and you won't have a problem with it growing back.
If you don't have a CO2 indicator, you may wanna check out this thread.
