You don't won't to use reef additives/nutrients in a freshwater tank. I would suggest Seachem/Kent/ Brightwell brand of nutrients.
You are on the light side with the plants, add more fast growers. Just remove all the algae you can by hand, trimming badly affective plants. Once you start a regular fert routine, get more plants & your tank becomes established you should see the algae disappear.
