  1. does the trick, easy to install

    Posted by Unknown on Jun 11th 2020

    This simple diffuser is quickly installed without having to take the light off the stand. I would suggest, however, that if you choose to do this that you put a barrier over your tank lest you drop a screw into your hardscape and have to struggle to get it out.

  2. t5 feel

    They're a little tricky to install but definitely give the tank an overall t5 feel.

  3. t5 feel

    Love these. They spread the light out more and give my main display a real t5 feel.
