I've had a glasscages 300g glass I loved but it was a bit heavy. It took 6 guys to move and lift onto stand. Now I have a Tenecor 750g acrylic which is great but scratches just by looking at it. My kids know to not even lay a finger on it. That took 6 guys to move as well. glass tank I used windex to clean the acrylic I use novus polish with a cotton t shirt
