First off, welcome to Tropical Fish Keeping forum.
I'll try not to repeat the correct advice kitten has given previously, just add some more on a couple of critical issues you've raised. Starting with the light. Plants grow by photosynthesis, and this they can only carry out in the presence of adequate light (intensity and duration) and nutrients of which there are 17. These include 9 macro-nutrients, like carbon, nitrogen, oxygen and hydrogen plus the minerals calcium, magnesium, phosphorus, potassium and sulphur; then there are the 8 micro-nutrients which are all minerals (copper, iron, zinc, manganese, boron, nickel, chlorine, molybdenum). These have to be in balance with each other, and the whole (nutrients) must balance the light. Pl;ants will cease to photosynthesize when any one of the essential nutrients (or light) is no longer adequate to balance the rest. This is when algae creeps in, since algae, while a plant, is able to "make do" better than plants.
Fish and plants need darkness in order to "rest." This, plus the fact that you would be highly unlikely to keep the nutrients balanced 24/7 is why the lighting must be controlled so there is a period of complete darkness. The best formula is 10 hours of darkness each 24 hour period. This can be increased, provided the plants still have sufficient intensity of light for a minimum period. Most suggest 10-12 hours of light, though slightly less and slightly more will work depending upon circumstances. I currently have 10 hours light on my tanks; you can see how heavily planted they are from the photos which are under the "Aquariums" tab below my name on the left.
Provided everything is available (all the nutrients and light), plants will photosynthesize and out-compete most algae. Algae takes advantage and increases when the balance is broken, usually with excess light. I mentioned the fact that plants cease photosynthesizing when some nutrient or light is no longer adequate to balance the others; this "minimum/limiting factor" should always be the light. Excess light regardless of everything else will always cause algae to increase.
Algae in itself is not harmful, and I allow it to grow on wood and rock. It is when it attaches to plant leaves that trouble can occur, as it prevents the exchange of gases and water through the leaves and the plant weakens. If things are kept in balance, in a planted tank algae should not be an issue of concern.
I would definitely reduce the duration of your light to 10 hours a day. If you get more plants and they are medium to fast growing, the light can be increased to 12 hours. You will need a liquid fertilizer to provide all the nutrients, as many are unlikely to be present solely from water changes, fish food, and organics breaking down in the substrate. I use and recommend Seachem's Flourish Comprehensive Supplement for the Planted Aquarium
; it is the best I have yet used. Make sure it is exactly the one named, they make several products in the Flourish line but this one contains everything (except oxygen, hydrogen and carbon which occur in the aquarium naturally). Anubias
is a very slow growing plant, and brush algae thus finds it an ideal host. Keep the Anubias
out of direct light, it loves shade and does much better under the shade of floating plants or larger plants like a sword.
At this point I will recommend that you have a read of the 4-part article "A Basic Approach to the Natural Planted Aquarium" at the head of the Aquarium Plants section of the forum. We also have plant profiles and fish profiles, second tab from the left in the blue bar across the top of the screen. And, all of us are more than happy to answer questions.
