After 5 years of fish keeping I'm upgrading my trigon 190 to a custom tank. What I would like to know is what thickness glass I should use. I have read a lot about this and 10mm seems to be the way forward but need to hear more opinions before making my decision, the tank will be 1000x500x700, if I have worked out the volume right, I should be looking at around 350l? Plus a 100l sump
Cheers
