First of all love the dimensions and volume, giggity... Wondering about you weir gap though, gigggity. Have you decided what you wanna use for power heads? If they create a wave then I have a concern you won't have consistent surface skimming through the overflow. I tried a 3/8 gap once like that, giggggity and the wave maker caused the water to pulse and kind of vapour lock. You might wanna add some vertical slots, or a bunch of them, just a thought. Or make the gap wide enough, ummmmm
, so to avoid this but not too big for snails to get lost in the back?.
Also, does the eurobrace cover the back overflow section or would there be access? I see a detritus trap down there
