Trigger system has hole I need to plug !

[jmichaelh7]

One of my trigger system sumps has a ATO hole that I capped off. Apparently it’s leaking around the hole. Any recommendations to plug it ? I can probably lower water level to apply something .

Thanks

do you have a pick? silicone will plug most items that don't have a ton of pressure (for acrylic).

What kind of silicone .

aquarium silicone... the other option (and maybe better) is to get a piece of acrylic slightly larger than the hole and just glue it over the hole (using acrylic cement). that would hold as well as an original weld.
