DIY:Screen Top

A few months back I bought a pair of Red Velvet Fairy Wrasses.  After owing them for about a month one of them jumped out of the tank and I didn't find it until the next day.  Needless to say I was sorta bummed but luckily there was still one left.  Last week I was watching my tank from across the room and watched the other one jump straight out of the tank and onto the carpet below.  Luckily I was there and was able to scoop it up and toss him back in in less than a couple seconds.  That's when I started thinking maybe a top of some sort was in order.
I ended up finding some black 3/8" nylon mesh and stretched across a DIY window screen kit I picked up from the hardware store.  I turned out pretty nice and only cost me around $15.
Here's a shot of it.

I have a bunch of the black nylon left if anyone needs any.  The black not only looks good but from what I can tell blocks very little light.

 

Sure thing man.
It is called light diffuser for a reason.  I'll be willing to bet this nylon blocks less than 10%.  I'll have to bring the PAR meter home tonight and test it.

 

I was thinking about going with the BRS clear netting but all they had was 1/4" or 1/2" mesh.  Being my tank is mostly black I went with the black stuff but 3/8" mesh. 
It would be cool to measure the difference in PAR levels between the 1/4" clear and the 3/8" black.  I'm willing to bet the 3/8" blocks less light just because it has bigger holes.
