Any Thoughts on Using This For An Aquarium Cover?

I use those and and really like them. I kind of believe the material is great at heat retention, but have no real data to back that up other than observation and speculation. 

They only drawback to them is if you accidentally dip them into the tank the voids can fill with water and, if you're not paying attention, this spills on your floor.

Other than that they work well and are easy to cut to size with a box cutter.

I have them also. They do well and I have added packing tape to the open ends because I found otherwise I would get fish food and pest snails in between the twin walls. They did seem to dim the lighting more relative to glass, but not enough to be a problem.

EDIT: I realized after I wrote this that they dimmed the tank relative to NO LID. I was surprised that it made as big of a difference as it did, visually, but my plants are fine.  Read on for actual statistics proving that this doesn't dim light more than glass.

Will it prevent much of the light from going through? That would be my concern.

I haven’t noticed any issues at all with light through these. But I don’t grown any difficult plants. My java moss and java fern do great under them with moderate intensity lights suspended about 6 to 8 inches above the lids. I believe these panels are used in greenhouse applications, correct?

I use something similar to this. I found poly sheeting like this in the light diffuser section of my hardware store. It works very well for aquarium lids. I think LRB aquatics cut his in half lengthwise and taped it with water resistant gorilla tape so he can open and close it easier. Taping the edges that are open sounds like a good idea too. Water does get in there. This stuff really cuts down on tank evaporation.

I have these on about 15 tanks and love how lightweight and easy they are to just move out of the way when I need to. 

When I first cut the pieces, I had an issue on my mbuna tank. The aquaclear filter clogged a bit while I was at work, somehow directed the flow straight to the back of the lid, which was open where it had been cut, and the water shot straight through it and out the front. Came home to a decent amount of water on the floor. I have since ran silicone along all of the edges that were cut. Learned my lesson there.

Yeah, I'd love to spend the time making semi-nice hinges for these because that's another complaint of mine about using these: picking the entire lid up.

One of these days ill spend some time figuring out how to make a decent hinge for these. Im sure its not super difficult.

Ive done the heavy duty tape thing for hinges on mine. So far it has lasted a year, I only replaced the tape on one, and it was super easy to peel off and replace.

Looks like it sure would work. As you're seeing, lot's of fish keepers use it. We use Lexan lids on about 7 tanks . . . two 55 gals, a 20 long, three 5.5 gals, and a tiny fry 2.5 gal. It definitely warps under heat and pressure. For our purposes, it's not overly distressing. We built it to flip symmetrically, and just reverse the bend upside down. Annoying . . . a little bit . . . but it works. Easy to clean, and it lets plenty of light through. This material you're suggesting might be less prone to bending. Here's a few photos . . .

Doh! I hadn't even thought of that! I'm so glad I read this thread. I'm getting ready to replace my glass lids with covers made of this stuff. The glass lids don't fit to suit my current needs, so I decided to make new covers out of this material after seeing Cory's video (he posted it above) and a couple of others on YT. I loved the idea of being able to make lids to suit me, instead of dealing with a one-size-fits-few approach. LOL

I’ve done some testing, these tops let more light through than a standard glass top because it has no iron to block light like the glass does.

 

Here is the video I did on these tops.

 

Glass is 83% light transmission while these are 86-88%.  Polycarbonate difuses the light which is actually better for plants.

No someone get Cory some safety glasses. At first I thought that video was, "how not to use a table saw".
