Silicone Type to Reseal Aquarium

[richiestang_78]

I have a old All Glass 10 Gallon that the silicone on the inside needs to be replaced but I'm not really sure what type of silicone to use. Do I need some sort of special high strength structural stuff or an I just use GE Silicone 1?

RTV 108 is stronger. GE 1 is aquarium safe from what I've heard but not recommended for tank builds. Although, it is probably strong enough for a 10g.

Thanks. Where can you buy RTV 108?

Your local hardware stores should sell it. Amazon has it along with several other websites. I believe aqueon sells tubes of silicone that is RTV 108 strength. Here's that product........
