Ok, so I want to build a refugium, for my 72 gallon Bowfront Reef, kind of a tuffy due to the bowfront design, so I decided to make my own out of acrylic instead of making it out of a pre existing aquarium such as a 20 gallon etc. so my question is can I make one completely out of acrylic? and if so, any ideas? or any one out there make one and have ideas, comments, photos? Thanks!
