...Water changes are one of the simplest most effective management tools available. Make them easy and if you bother to do them, go big % wise.
... Many want these nice scapes that require work, and also want/or just buy.....high light, then do not want to do much to keep up on it, that is not realistic.
All so true. Water changes help every setup. It's not only ferts, but removing excess organics helps all setups assuming your feeding your plants.
Don't believe for a minute that for example a full ADA setup maintains itself. They are all built around the water change and even with that algae will form. It's all about lifestyle and what your willing to do. If your not willing to get involved on a regular basis then your focus should be low light, easy plants and low stock setups.
