Remove Internal Glass Overflow

[Darwin stinton]

So I have a 120 Gallon tank with two internal Glass Overflow's. I want to know if anybody has got a proven method to remove the silicon from these? My reason is that I want to install two External Overflow's and free up space and get rid of those ugly overflows. Crazy Maybe!

Thanks

Just cut the silicone holding the overflows in place and then scrape the remaining silicone. I have done it before without an issue.
