I've been exploring cheap diy aquarium lids and I was curious about this plastic hobby lobby sells. Its clear, fairly thin, comes in decent sized sheets, and cuts real easy. I don't believe theres any specific labeling for it besides "plastic sheet", would it be safe to use or am I better off looking elsewhere? Originally got some glass aqueon lids but unfortunately they don't fit just right :/

I can’t imagine it would be unsafe for your fish. However if doing live plants may be a different story due to not knowing how much light it may or may not diffuse.

Do you have a link to the lids your looking at? I had lids on all my tanks at one time then one day i got sick of cleaning them and removed them all and have never had a jumper. Everyone has a different experience i know but if your water parameters are all good 99% of the time inhabitants will stay in your tank aside from an occasional snail escapee....

This isn't the exact same as what ive seen in stores but I believe its the same material. And while I'm mildly worried about jumpers, I'm more concerned about the light I have for the tank since it isn't waterproof and my lizards. They're in the same room and they need low humidity, so I want to minimize as much evaporation as possible

none are really 100% waterproof but if you have minimal surface agitation from a canister, hob, or sponge it usually isn't an issue. I don't have reptiles so i can't comment on that part of your concern sorry. Best case would be to find the product you wanna use as a lid and contact the company direct to see if its food safe. That way if its food safe its fish safe.

Hi,
Just a thought but a friend got some fluoro plastic from a lighting store. The type that is smooth on one side and has the tiny pyramids on the other side in a clear plastic. Gives really good light diffusion and I think he said it was pretty cheap.

I'm using polycarbonate for three tanks. I got a pack of three 24x12" sheets for $25 or so on Amazon and cut to size with boxcutters and some sort of pruning shear/maybe craft shears. Lowe's and Home Depot have the brand name in single sheets of various sizes. The ones I got say something like "for robotics" but I don't think it matters much... They may be a cheaper knock-off than the brand names (LEXAN is the most known, I think), but I don't know for sure. They work, is all I know!
And polycarbonate is stronger than glass and acrylic, pretty much shatterproof. They are flexible a bit, but that's why they won't break or shatter.
Actually it contains heat and evaporation/condensation a bit too well if you cut to perfect size with little or no gaps... I lifted the lid off my divided betta tank and felt the warmth and the lid has lots of condensation on it.

Oh it’s totally fine.

I decorate my tanks at Halloween and Christmas with little plastic ornaments I get at Michael’s. And I’m sure the paint those use are much “less safe” than a plastic sheet. Still, they’ve never caused any issues in my tanks.

I don't think they'd be toxic but I expect they'd warp pretty quickly because they're thin. I have very thick plastic sheet cut from a hardware store and it still bends.

Have you looked at the Marineland tops? They fit a bit differently than the Versa-Top lids, though offhand I can't remember which is bigger.
