over feeding long of light period.not enough fertilizer or much fish poop.bioloical filteration not up to sufficent level.tap water is high in ammonia.
More gas, that nearly always makes it stop spreading. Spot treatment with flourish excel should kill what you have in there now.
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.
