Fish safe silicon?

[hillsy]

Just wondering if anyone could recommend any silicon to use to seal pipe work and a viewing window I am cutting into my IBC fish tank? Is there a special "fish safe" silicon I need to use or will ordinary roof and gutter silicon do the job? Also do I just use standard PVC glue on pipe joints?

Yep standard pvc glue and i have always used sellys roof and gutter [so far no problem or leaks in 3 years]

I always look at the silicon tube and see if its aquarium safe...

Hi folks

I'm the same as fish food I use the blue glue and prime my joints before adding glue for the PVC,and roof and gutter sealant for joining up my liners,works for me.

Cheers.
