Hey everyone! I have a 55 gallon aquarium that I would like to set up in my 3rd grade classroom. I really want to teach my class how to set up and maintain an aquarium since most kids give up on fish tanks due to the fish dieing. Plus, I think there is just a lot of responsibility that can be taught as well. I have everything I need except a heater and filter. I am on a budget but would like to get items that will work well in a basic 55 gallon freshwater tank. I wouldn't mind getting two filters for the tank. If you have anything available let me know! The kids and I are excited to get everything started! Thanks for any help!

I am also looking for an air pump as well. Thanks!
