Rimless tank assembly - Which silicone?

[Dr4gula.f32]

There is a Red Sea reefer in my town for 200 complete. Owner says it does not leak but does not recommend filling it unless totally rebuild. For 200 bucks, it might be worth it? What silocone would be used for this? Seems it would need some structural integrity since there is no frame to hold it all together@!

I've always been a fan of Momentive RTV 108 ( clear) or RTV 103 ( black)

This is good to use on a rimless tank? It has enough structural integrity to hold it together AND seal water?

might as well put braces on them if you're going to rebuild it.

I've made a few rimless tanks with RTV 103. These weren't that big, under 60 gallons.
But seeing what people are saying about rimless, I would consider adding a eurobrace on anything bigger that 75-100 gallons.

I think the price is a bit steep for a leaker… I usually get them free, considering what a pain it can be to break a tank down!

You do have a good point.
I bet hes willing to take half of that and i bet he REALLY needing someone to remove it from his property.

RTV 103 would be what I would use.

And if still worried, could probably make a template and take it to a glass shop for the top if you want.
