Fish safe adhesive

[JohnG123]

Hi, in the process of cleaning my Nyos skimmer I inadvertently loosened a post which holds the diffuser. Can you recommend a fish safe adhesive that sets hard?

Since it appears to be acrylic, if it were me I would buy some Weld-On #3 or #16.
With #3 you would need to buy an applicator bottle too. With #16 which is thick, straight out of the tube.
