CDA does armored seams, I did the full reinforced in case I wanted to go for the bare bottom. Although I love jawfish a little too much so will end up needing lots of sand…
Went with 1/2” with CDA since it’s 180G, if I were to go bigger would have done 3/4” but I used to have 360G in acrylic so didn’t want to go bigger lol.
Considered T-Slot too (contacted FramingTech), CDA doesn’t do T-slot. But you can also play around building it on vention.io too. Mine was more of wanted to match the current cabinet look - so went with CDA (also they do marine expoxy grade paint instead of powder coating) and increased the height to 40” as well.
Zoya(CDA) is great btw- I considered adding a back extension to have “hidden space” and she recommended another metal piece that could be detached/attached and could have made the canopy extend to cover the “hidden space” too (did scratch the idea because since I can customize my sump - I should have enough room for ATO reservoir). I’m the opposite of you, I’m not sure I’m in my forever home- so I didn’t want anything to be built into the house, haha.
Glass Cage/Joe is awesome too- honestly the fastest response and great pricing as well. CDA was better with cost in transportation since I live in CA.
Red Sea does come with t slot but they are pretty thin… don’t remember the exact but def less than .75” (went to go measure in person). Framing tech’s t slot looks a lot more solid - depending on how paranoid you are lol.
I think it also depends on where you live bc the cost of the tank can increase from 350 to 1300.
