The more light you use, the more maintenance you will have to do. Light drives the plant growth rate, so more light means more pruning and other plant maintenance. Algae love light, so the more light you have the more likely you will have algae problems, which take additional maintenance to control. The more light you have, the more fertilizing you will have to do to keep up with the plants demands for nutrients. And, the more light you have, the more you need to use pressurized CO2, and keep it adjusted to give you an optimal concentration of CO2 in the water - CO2 systems need regular maintenance.
Limit your lighting to around 30-40 PAR and "low maintenance" becomes possible. This is offset by the limit on what plants you can grow, the limit of how colorful the plants will be, and how few "carpet" plants you can grow successfully.
