Begin with a consistent day
Neocaridina do not need bright lighting for their own sake. Plants need light, but long or intense schedules can encourage algae when nutrients and plant growth are out of balance.
A simple timer helps keep the photoperiod steady. Start conservatively based on your plant choices and light strength, then observe the aquarium for a few weeks.
Respond to what the tank shows
If algae spreads quickly, review light intensity, duration, nutrients, and maintenance together. Do not make several changes at once, because it becomes difficult to identify what helped.
Avoid turning lights on and off unpredictably throughout the day. A stable schedule is easier on plants and makes shrimp behavior easier to observe.
For your own tank
Adjust the schedule by small increments and give the tank several days before judging the result. Keep a timer setting written down so a power interruption does not create an unpredictable day. Plants, algae, and shrimp visibility all help you evaluate the balance.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
