Good point. If you use 100% silicone it should be more than enough.
Amazing Goop, available at Lowe’s and other stores is awesome. Some of the strongest stuff i’v used. Have it in some tanks for over 10 years and still strong as new. It is amazing goop.
but as mentioned, 100% silicone works. It’s what all the tank manufacturers use to attach their acrylic overflows to their glass aquariums without issue.
Scrape clean, wipe with alcohol, re-attach
Nice to know. Thanks for posting.
