The brown stuff is Diatoms and the red stuff is Cyano (its actually a bacteria and not an algae).
Both are feeding on nutirent rich water. This is usually normal in a new tank as the tank is trying to stabalise. Howver if you keep adding tap water then you may well be feeding the tank with more nutrients and thismeans getting rid of the algae will be very hard indeed.
You could try introducing some macro algae to outcompete the nusance algae. Start using Ro water as this will make an enourmous difference. Get some Rowaphos also, this will help remove phosphates and this is a major cause of algae outbreaks alongside high nitrates.
