Yes, the Aquapod is glass. I have the 24 Gallon. I love it. I just used an old credit card to clean the stubborn algae off my tank this morning. This was a trick I learned thanks in part to the owner of Coral Dynamics, here in NC. Now, of course if the Aquapod was made of acrylic, you could not use the credit card technique to clean it b/c it would scratch. The technique works just like the other algae scrappers you can buy in the store, but in this case it is free.
