Neptune Systems SKY Diffuser Kit

SKY Diffused Shimz allow for on-the-fly tweaks to the shimmer produced by your SKY light without the need for any programming or adjustments to light settings. Out of the box, the SKY has four openings in the diffuser where white LEDs can shine through undiffused. With typical surface water turbulence, this provides a gentle shimmer that most aquarists will find to be a good balance, but if you find this to be too much, Neptune Systems created an option for customizing the shimmer by changing out the clear covers for diffused covers. The Diffused Shimz inserts simply pop in and out of the four white LED sections of the diffuser panel in seconds and you can visualize the changes immediately.
