The brown spots are brown algae, and there are brown algae hairs growing off the end of the broken leaf in the foreground. It rubs off with my finger. I'll head to the algae forum to ask for advice.
Tank is still cycling, the Ammonia has dropped to 0 but the Nitrites are still at ~5.0 PPM, I expect them to start dropping soon. I change about a gallon of water every other day. I am using Amquel+ and NovAqua+, I switched to tap water from purified water, the Flourish Tabs are still in the gravel and I am doing ~5 drops of Flourish Excel every 3 days at the moment.
I am considering Water Sprite in the tank to provide some floating greenery, I like the look better than Dwarf Water Lettuce.
