Time to Upgrade!

Plastic cover or plastic rim? If the latter, you should research using foam in that application and/or contact Lemar and ask them.
 
I think he means the plastic sheeting that comes on glass to protect it (looking at the picture/type of tank). You are correct though, you wouldn't want to use foam on a tank that has trim, but on trimless tanks foam is very important to ensure the glass is distributing the load evenly. If the wood/top isn't perfectly flat (hard to do) it can cause issues for trimless tanks.

On the light hangers, did you use some metal L brackets to reinforce the joint? I would be afraid of relying on screws/glue alone when it comes to a light hanging over water.

I will be adding brackets when I hang the lights. I did use pocket holes and screws and glue.
 
I have not but have seen a few in action. I did not like the size of even the small one I saw. Kind of an eye sore unless you can blend it in somehow. The water movement was good but I didn't like the teetering water line in a rimless tank, really distracting. I was also not a fan of the way the corals moved. It was like they were head banging :).
 
I agree, wavebox is too big and too noisy. It does work as advertised, but I agree with Greech, on a rimless tank, I would avoid making any type of waves. The pressure that the waves create by pushing the water back and forth can make a rimless tank split apart at the seems under the right circumstances.
