G/flex epoxy

[1MADMAN1]

I recently got G/flex epoxy at my local marine store it seems like it would work for what iam wanting to do
I have a 20 long that I want to turn into a sump for my 55 gal
So iam wondering if anyone here has used this product before and if they think it will be safe and not leach anything into my tank

What do you want to use it for?

I wanted to use it to hold the plexiglass to the glass tank making baffles for my sump then silicone edges to seal the g/flex seems way stronger than just reg silicone

Silicone is more than sufficient on its own to make baffles in a sump. Sealing cracks or tank walls under pressure = no. Simple things like baffles are no issue though
