I have a small air pump that works except for the fact the nipple broke off when I was moving things around. This means I have no way to connect an airline to the pump! The nipple is recessed, and I have an open tube of clear, silicon-based gutter sealant ready-to-hand. I had thought I could take a section of airline, place it over the pump outlet, the seal up the recess. Normally, for aquarium repair work, I would use a food safe silicon, but a tube of this stuff does not cost significantly less than a new air pump, and it tends not to store well once opened. Does anyone know if using a non-food safe sealant would be safe for the fish in my intended repair? If not, I’ll put the pump into deep storage until I need the appropriate sealant and buy a new one.
