Due to the lack of availability and the high prices of cube tanks. I've decided to make one myself. I have various glass shops near so no need to travel long distances. The main focus is going to be planted and nano reef tanks. I figure that an 18" x 18" x 18" tank an another in the 24" x 18" x 20" will make good displays. Even an 18"x18"x 10" would be good enough. I guess my question is, what glass, tempered? and the thickness? These tanks will probably be made for customers, after they sign waiver papers of course
