hello im going to be building a plexyglass viv tank from nothing to everything.
What about people using them for fish tanks? That's a lot of moisture.Even thick plexi glass will warp under vivarium conditions. The material will absorb more moisture on the inside of the viv than the outside because of the difference in humidity, which causes the bowing effect. The fans might help, but eventually the plexi glass will bend to the point where the occupants could escape. I strongly suggest going with glass (at least for the lid).
I don't know a whole lot on this subject, but my guess is it has to do with the pressure that the water puts on the plexiglass. This acts against the material's desire to bow inwards towards the moisture.What about people using them for fish tanks? That's a lot of moisture.
I know what you say is true tho but its weird tho that people can use it to make fish tanks.
What about true acrylic sheets?
