That's exactly what I use, and don't have a single salt water fish which could make it through there. Even small clowns would bang their little heads pretty bad. I've never had a single jump, and I've been using it for a long time. I learned about it from other aquarists.

I also cannot tell the difference in light from a bare top to the egg crate. The inverts don't seem to either. It's actually made NOT to restrict light. I should have called a "lighting panel" NOT a diffuser.

Because of scratches and salt spray, I've found egg crate restricts light less than glass or plastic.

I use an Artfully Acrylic custom top with Acrylic mesh (1/4). No noticeable impact on light intensity, 98% open for gas exchange, aesthetically great. Not cheap but a quality product.

BRS sells DIY versions.

When I had my 300 I used the BRS screen that I purchased from my LFS. It worked great never lost a jawfish, the only issue was the screen was not UV rated and I had to replace every couple of years which was no big deal but I went through two Trane fan blower motors on my ac. Since going to my 180 with glass tops no issues. In my office I have always had either a glass top or Poly carbonate to help with dust and cleaning people.

Why would anyone use plexiglass/acrylic instead of glass for this application? More expensive and much worse light transmission.

My tank top is a piece of glass I bought at HD and cut to order. I think it cost $8. Perfect light transmission, cheap, no holes for jumpers.

I hear the concerns about gas exchange but if you have a sump and a skimmer (and why wouldnt you?), you already have more than enough gas exchange.

Besides breaking, glass tops get a cloudy/milky haze over time. But for $8, I guess you could replace it.

People put light diffuser on their lights, so why would this be a bad thing. You would have to have very small fish to jump threw the holes.
