Where to get economical polycarbonate?

[PotatoPig]

I’m trying to make a lid for my aquarium to discourage carper surfing and was planning of using polycarbonate for a little easier drilling/cutting.

Currently have glass, with a gap at the back for the HOB and return pipe, but want to close this off. Plan is to have a pegboard-style panel with lots of holes to allow for air circulation.

Does anyone have suggestions on where I can obtain economical polycarbonate panels?

I use egg crate light diffuser panels. Like $15 at HD and Lowes.

Oh, I hear ya on those. Unfortunately unless they’re clear (I’ve only seen white) they’re not gonna pass the Spouse Acceptance Factor test.

Try McMaster- Carr Supplies.

An online plastics shop may be your best bet, something like tap plastics is a staple and has been around, but shipping can get you.

If you want to risk it, you can try getting a piece of that sort of corrugated open-center translucent polycarbonate - I ordered a sheet from home Depot (had to be delivered to the store) and ended up with a quarter inch thick of solid clear polycarbonate

I'm using the white egg crate on my rimless cube, its more tolerable than you think. Almost translucent and is more forgiving to par loss.

Are you referring to clear polycarbonate like a Plex panel or the usually used twin wall polycarbonate?




Go to 3:50-ish

Pretty sure both plexiglass and plexiglass like poly ( you know looks like glass) warp over an aquarium.
Sag or warp....

Regular polycarbonate will sag if the span is long enough regardless of thickness. The stuff they use for green houses which is the twinwall will not since its structure style is more rigid.
If you do have a local plastics shop it would usually be a lot cheaper to get it from them (even custom cut) or sometimes they have minimally damaged/unsellable sizes that might suit your purpose that they will straight up give you.

Below is an example of my friends 1/2" polycarbonate sheets on his 375 with a very noticable sag.
