Like med said consistency is the key regular routines and light schedules try to learn and read as much about algae and on how your equipment works as possible. Their are different types of algae some good some bad , the bad stuff is alot easier to orevent then get rid of and the good stuff doesn't happen over night bu will in time
another thing to remember is f this is a fairly new system you'll probably deal with your share of algae over the next year don't get frstrated and ask ask ask , I'm sure the algae subject will never end people are always finding new ways to deal with things so knowlege is your best defence the rest are just small tasks
cheers!!
