Getting some plumbing done, one more gasket should come today so I can get rubber between the overflow and the tank. I know you don't "need" that one, but I had so much trouble with my last overflow leaking, I am likely going to silicone everything first go.

Hit me up and you guys can cool off in the tank, or pool. If you come next year, I'll have you bring coral.
Don’t believe them when they say you don’t need three gaskets. I have three marine modular overflows running right now and had five running at one point. Every single one leaked or had some salt creep that did not have a gasket between the OF box and tank glass in addition the two gaskets between overflow box and nut and the flange and tank glass. In theory, you shouldn’t need it, but in practice, I’ve needed it.
I’d avoid the silicon, you should be fine with three gaskets.
