You suggest 20mm because 15mm won't hold or it will bend? Or just to be sure about the tank?20mm^^
15 won’t hold. Finding 5/8” acrylic is difficult as well.You suggest 20mm because 15mm won't hold or it will bend? Or just to be sure about the tank?
Here in Greece its easier to find 5/8'' than 1/2. thats why i ask if it will be ok because all guides says 1/2'' for my height and i went a little up from there.15 won’t hold. Finding 5/8” acrylic is difficult as well.
