Chihiros - C series

Chihiros C series is a perfect fit for rimless aquariums ranging form 20cm to 40cm length. 
Works good for low tech plants and works well as a medium light module for tanks ranging from 5-30Gallons.
Keep in mind for 20/30Gallons, you may require 2 modules to cover the entire surface area.
If using to keep low light plants, or easy to grow plants, you can stagger the placement by picking a C361 module and place it where your high light requirement plants will be planted.
Anubias/ferns/bucephalandra can essentially be planted in the areas of low reaching/penetration for your C series light.
