starsman20 Posted March 15, 2021 Share Posted March 15, 2021 I've watched a bunch of videos on making lids out of corrugated polycarb they use for greenhouses. Has anyone used cast acrylic or lexan? I have extra of both for free. Since some tanks are now acrylic it seems that could be used and have better light transmission. Thoughts?? Link to comment Share on other sites More sharing options...
