to be honest i'm not totally sure its thick enough, certainly looks it though!notanatheist;4463753; said:25mm acrylic? Is that going to be thick enough? My tank is going to be 40" high and I'm wondering if I can get away with 3/4" with bracing on all sides. If your 25mm holds up at that height surely 3/4" will work for me!
