check this guy's tutorial, he offers a lot of cheap DIY method for aquariums and tanks, even by making your own stand. This video shows u how to make ur own aquarium stand and canopy, with this we can only buy a big [---] aquarium and careless about the stand's price becuz we are gonna make one ourselves! I think his idea is great and it really benefits us( turtle keepers when large tank is a minimum requirement).
