Awesome tank. Subscribed for the Achilles my dream tang but I'll need a bigger tank first.
Very nice sump what glue did you use and did you cut it all your self?
I used acrylic glue the one that sets in 7 sec, looks like water. I used heavier cement acrylic gel 16 as reinforcement for piece of mind.
I had a company cut 60-70% since Cnc, water jet or laser is expensive, mainly straight edges. You can cut with a 80 tooth carbine blade run $50+. Don't use standard table saw blade.
