You're probably looking at HD, which is more expensive, for sure, and I don't think they even carry the 1/16 size. I see there is an Industrial Plastics in Calgary. They should carry it, and be a lot cheaper. Like I said, I can get a full 4' X 8' sheet from them for $90. They might have smaller cut pieces available for less too. But at worst they will cut you a smaller piece, for a small premium.

I clean mine about once a month. It only gets "dirty" if water from a return or pump splashes up someplace. Same with salt creep, only happens where water can splash. But you would have the same with mesh or egg crate, and it would be a lot harder to clean.

Just don't use acrylic or some other kind of plexy. That stuff will bend and warp over time, and has to be a lot thicker (more expensive) to have any strength. And it shatters and cracks really easy.
