Diy sump

[Fishko]

About a year ago i buildt my own sump from a 20g long. I used the ge silicone 1 and cut the glass and everything. I used an apropriate amount of silicon and tested the sump for about two weeks to be absolutly sure that there were no leaks. Today i was cleaning out my skimmer and wondering what were the chances it could start leaking. Or something bad happen. For spring break my friend is helping me finish my stand which is half done. Im plan on upgrading to a 10g aquarium. But just wondering if the sump is holding up this long coming up to a year then is it buildt well?

you're fine in my opinion.
I have entire (small) tanks I've built the same way that are still holding water just fine.
