silicon for sump

DML08 · 04-11-2008, 12:45 AM

I'm doing a DIY sump... i have a old glass tank(donated by edd13) i went out and bought some acrylic from Lowe's. i have everything glued in place, started to seal the seams with some aquarium silicon but ran out (bought the last 2 tubes at the LFS) so my next spot is HD or LOWES. so what kind do i pick up?

cylicone will not adhere to acrylic
Weld on does, but weld on will not adhere to glass

GE I is safe. GE II not safe

so will the build work? or seal up properly? for acrylic to acrylic I used acrylic cement.. now i need to seal up glass to acrylic and go over acrylic seams with some silicon... or do I?

I didnt find anything that could attach acrylic to glass and was fish safe
maybe someone else here knows a secret?

I just had the hardware store cut some glass for me
